Through watching the congress celebrating the 100th anniversary of the founding of the Communist Party of China, I deeply realize that the Communist Party of China has always regarded working for the happiness of the Chinese people and the rejuvenation of the Chinese nation as its original mission. Countless Chinese Communists have worked tirelessly for this mission. Their struggle and sacrifice have brought us a strong motherland and a happy life for the people today, We should inherit the glorious tradition of revolutionary martyrs, never forget our original intention, remember our mission, adhere to the purpose of serving the people wholeheartedly, hold high the banner of communism, and strive for the cause of communism for life!
