2022 belongs to the 21st century. The 21st century starts on January 1, 2001 and ends on December 31, 2099, so 2022 belongs to the 21st century.

Century refers to the unit for calculating the age. When used to calculate the date, the century usually starts one year after the year that can be divided by 100, such as 2001.

The century is derived from Latin, and this odd number dating method comes from the era after the Jesus era. One year usually means "the year of our lord", so the first century is from AD 1 to AD 100, and the 20th century is from AD 1901 to AD 2000. Therefore, 2001 is the first year of the 21st century.

Time unit conversion:

1. The first century=100 years.

2. 1 year=12 months.

3. January=30 days.

4. 1 day=24 hours.

5. 1 hour=60 minutes.

6. 1 minute=60 seconds.

7. 1 second=1000 milliseconds.

8. 1 millisecond=1000 microseconds.

9. 1 microsecond=1000 nanoseconds.

10. 1 nanosecond=1000 picoseconds.

Hunan Province is a provincial administrative region of the People's Republic of China. It is a province in itself, and does not belong to any province.

On August 5, 1949, Hunan was peacefully liberated. On August 19, the Military Control Commission was established. On August 29, the people's power was established. Then 10 commissioner offices were established: Changsha, Hengyang, Chenxian, Changde, Yiyang, Shaoyang, Lingling, Yongshun, Yuanling, and Huitong, with 77 counties under their jurisdiction.

Hunan Province is located in the middle reaches of the Yangtze River, and most of its territory is south of Dongting Lake, so it is called Hunan; Xiangjiang River runs through the north and south of the province, so it is called Xiang for short. To the east, Mufu and Wugong mountain systems border Jiangxi; To the west, it connects Guizhou to the east of Yunnan Guizhou Plateau; The northwest is adjacent to Chongqing with Wuling Mountains; The Nanling Mountains in the south are adjacent to Guangdong and Guangxi, and the lakeside plain in the north borders Hubei. The provincial boundary extends east to Huanglianping, Guidong County, west to Jiucaitang, Xinhuang Dong Autonomous County, south to Gupo Mountain, Jianghua Yao Autonomous County, and north to Huping Mountain, Shimen County.

Hunan is located in the transition zone from the Yunnan Guizhou Plateau to the Jiangnan hills and Nanling Mountains to the Jianghan Plain. It is located in the eastern extension of the Yunnan Guizhou Plateau and the southern end of the southeast hill turning line, which is gradually reduced from west to east. There are various geomorphic types, including semi high mountains, low mountains, hills, hillocks, basins and plains. In the east, there are mountains separated from Jiangxi, including Mufu Mountains, Lianyun Mountains, Jiuling Mountains, Wugong Mountains, Wanyang Mountains and Zhuguang Mountains. Most of them run from northeast to southwest in a wild goose line, with an altitude of more than 1000 meters. In the south is the Wuling Mountains (Nanling Mountains) composed of Dayu, Qitian, Mengzhu, Dupang and Yuecheng mountains. Most of them run from northeast to southwest. The mountains are generally east-west, with an altitude of more than 1000 meters. The west is the Xuefeng Wuling Mountains from northeast to southwest, which spans a wide area and forms the dividing line between the eastern and western natural landscapes in Hunan Province. The north section is 500 to 1500 meters above sea level, and the south section is 1000 to 1500 meters above sea level. Huping Mountain in Shimen County is 2099m above sea level. In central Hunan, most of them are intermittent red rock basins, limestone basins, hills and terraces, with an altitude below 500 meters. In the north is the lowest and flattest Dongting Lake Plain in Hunan Province, with the altitude mostly below 50 meters; The lowest point of Yanghu embankment in Yuelu District of Changsha City is 21.6 meters above sea level, which is the lowest point in the province. The geomorphic outline of Hunan Province is surrounded by mountains in the east, south and west, with hills in the middle rising and falling, and the lake basin and plain in the north spreading, which is an asymmetrical horseshoe shaped terrain opening towards the northeast.

Hunan has a continental subtropical monsoon humid climate with three characteristics:

1. Light, heat and water resources are abundant, and their high values are basically synchronized.

2. The climate changes greatly within the year. The winter is cold and the summer is hot. The spring temperature is changeable, the autumn temperature drops sharply, the spring and summer are rainy, and the autumn and winter are dry. The interannual climate changes are also large.

3. The most obvious vertical climate change zone is the mountainous area surrounded by mountains on three sides. Especially in the mountains of western and southern Hunan.

According to the statistics of meteorological stations in various counties in Hunan, the annual average temperature is generally 16 to 19 ℃, the average temperature in the coldest month in winter (January) is above 4 ℃, and the average number of days with daily average temperature below 0 ℃ is less than 10 days per year. The average temperature in spring and autumn is mostly between 16 and 19 ℃, and the temperature in autumn is slightly higher than that in spring. The average temperature in summer is mostly between 26 and 29 ℃, and it can reach as high as 30 ℃ in Hengyang area. Hunan has sufficient heat, and the daily average temperature in most areas is 5600 to 6800 ℃ through the active accumulated temperature above 0 ℃; The active accumulated temperature above 10 ℃ is 5000 to 5840 ℃, lasting for 238 to 256 days; The active accumulated temperature above 15 ℃ is 4100 to 5100 ℃, lasting 180 to 208 days; The frost free period is 253-311 days. Hunan's thermal conditions are second only to Hainan, Guangdong, Guangxi and Fujian in China, close to Jiangxi and better than other provinces.

The second generation ID card is 8.56cm long, 5.4cm wide and 1cm thick.

The second generation resident ID card is a single page card certificate made of multi-layer polyester material, which is made by non-contact IC card technology and has two functions, namely, visual reading and machine reading.

The front of the certificate has the issuing authority and validity period, and is printed with the national emblem, the name of the certificate, the freehand design of the Great Wall and colored patterns (the pattern is rainbow twisted rope pattern, and the color is light blue, light pink, and light blue from left to right); The back of the certificate is designed with seven registration items: name, gender, nationality, date of birth, address of permanent residence, citizen ID number and personal photo.

The second generation of resident identity cards was implemented in accordance with the Law of the People's Republic of China on Resident Identity Cards adopted at the 3rd meeting of the Standing Committee of the Tenth National People's Congress on June 28, 2003. Compared with the first generation card, the second generation card mainly has the following changes:

1. The chip has large storage capacity.

The new ID card adopts non-contact chip, and the written information can be classified into security levels, stored in different areas, and has larger capacity.

2. The appearance of the certificate changes.

The certificate shading adopts rainbow printing technology, and the color ranges from light blue to light pink to light blue from left to right. On the back of the certificate are the photo of the holder and the registration items (name, gender, nationality, birth, address and citizenship number).

3. Digital anti-counterfeiting technology.

Digital anti-counterfeiting is used for anti-counterfeiting of machine-readable information. Digitizing the photo image and identity project content of the holder, encrypting them with password technology and storing them in the chip can effectively play the role of anti-counterfeiting certificates and prevent forgery of certificates or tampering with the machine-readable information content of certificates.

The second generation ID card adopts two anti-counterfeiting measures:

1. The certificate chip adopts digital anti-counterfeiting measures, which can complete authentication when the certificate is read by machine.

2. The certificate surface adopts anti-counterfeiting film and printing anti-counterfeiting technology. The anti-counterfeiting film adopts directional photochromic film with independent intellectual property rights and other technologies. The printing anti-counterfeiting technology includes fine shading, microfilm, rainbow printing, and hidden encryption points and deformed encryption words in the printed pattern.
Some of these new anti-counterfeiting measures can be observed with the naked eye:
1. At the location of gender projects, there is a directional photochromic "Great Wall" pattern, which may be yellow with the left eye, green with the right eye, and blue with both eyes; Day and night show different luster.
2. The words "China" stored in the photo are dimmed.
3. With a magnifying glass, one can see that there is a miniature string "JMSFZ" in the shading of rainbow printing.
4. If the front of the certificate is placed under the ultraviolet light, the fluorescent printed "Great Wall" pattern can be found.

Fujian is located in the southeast of China and on the coast of the East China Sea. It faces Taiwan Province across the Taiwan Strait to the east, Zhejiang Province to the northeast, Jiangxi Province to the northwest across the Wuyi Mountains, and Guangdong Province to the southwest, connecting the Yangtze River Delta and the Pearl River Delta. It is an important outlet to the sea for mainland China and an important window and base for China's exchanges with the world. The land area of the province is 124000 square kilometers, and the sea area is 136000 square kilometers.

Fujian has towering mountains, rolling hills, valleys and basins. Mountains and hills account for more than 80% of the total area of the province, known as "eight mountains, one water and one farmland". The terrain is generally high in the northwest and low in the southeast, and the cross section is slightly saddle shaped. Under the control of the Neocathaysian tectonic system, the western Fujian mountain belt and the central Fujian mountain belt are formed in the west and middle of the province, with the north (north) east syncline running through the whole province. The two mountain belts are separated from each other by river valleys and basins, and the eastern coast consists of hills, platforms and coastal plains.

The land coastline is 3752km long, dominated by coastal erosion landform, followed by accumulative coast, and the coastline is very tortuous. The intertidal zone has a tidal flat area of about 200000 hectares, and the bottom material is mainly mud, silt or sand mud. There are many harbors, including Shacheng Port, Sanduao, Luoyuan Bay, Meizhou Bay, Xiamen Port and Dongshan Bay from north to south. There are more than 1500 islands scattered all over the country. Pingtan Island is now the largest island in the province. The original Xiamen Island, Dongshan Island and other islands have built seawalls to connect with the land to form a peninsula.

Fujian has a subtropical marine monsoon climate, warm and humid. Fujian is close to the Tropic of Cancer. Influenced by the monsoon circulation and topography, the accumulated temperature of ≥ 10 ℃ in 70% of the regions of the province ranges from 5000 ℃ to 7600 ℃, with abundant rainfall and sufficient sunshine. The annual average temperature is 17 ～ 21 ℃, and the average rainfall is 1400 ～ 2000mm. Fujian is one of the provinces with the richest rainfall in China. The climate conditions are superior, suitable for human settlement and the growth of various crops. The climate varies greatly from region to region. The southeast coastal area of Fujian has a subtropical climate, while the northeast, north and west of Fujian have a subtropical climate. The vertical differentiation of water and heat conditions in each climate zone is also obvious.
