A nation will prosper only when its young people thrive; a country will be full of hope and have a great tomorrow only when its younger generations have ideals, ability, and a strong sense of responsibility. Young people always play a vanguard role in realizing national rejuvenation, which is the mission of the Chinese youth in the new era. In China many young people realize the value of life through hard work. They are writing a brilliant chapter worthy of our times in their efforts to take advantage of their youthful vigor, explore life and contribute to society. (Xinhua/Xiong Qi)
