I recommend the following three lightweight books that are easy to use in 2021. I think they are quite good, and I hope they can help you.
1. Lenovo Xiaoxin Pro 13
Very good performance release, excellent screen
2. Lenovo YOGA 13s 2021
Cost performance: If you pay special attention to the appearance and workmanship or are used to MacBook and xps, you should not place an order. It is essentially a 5000 file computer.Running speed: OK. Since Windows is not activated, the test software cannot be downloaded, and I don't know whether the 4k video of station B can be played smoothly.Screen effect: The screen has no bad spots, no light leakage, and no graininess. However, the color is slightly yellow compared with the display, and the brightness is significantly darker (the appearance under the maximum brightness of the computer).Heat dissipation effect: OK, Lenovo computer butler shows the CPU temperature at 51 degrees.Appearance design: very light and thin.
3. Lenovo Xiaoxin Pro 14 2021 Standard Pressure Ruilong Edition
