Recently the “China dream” has been the subject of a public topic. Although it is quite common for Chinese people to dream of an empowered or a prosperous(繁荣) China, most people also have their own dreams. Throughout China’s thousands of years of history, these “China dreams” have always existed. Do you have a “China dream”? I brought up this topic with several young Chinese students with higher U.S. educational backgrounds. Unsurprisingly, they all had their own heartfelt hopes and dreams for their native country.

Fred Wang, an MBA candidate in the U.S. said, “I dream of equal chance for the young in China. Equality means all young people can compete fairly, based on the rule-of-law no matter whether they are rich or poor.”

Yujie Zhao, another MBA candidate in California said, “I dream of a happy family with an affordable home. I dream of having the best education for my children so they will not lose at the starting line, and I dream of being able to take good care of my parents after they retire(退休).” She said, “It seems like all my dreams are about family, but it is so true for most Chinese young dreamers today.”

Yiqiong Zhang, an MBA graduate from the US shared her dreams. “I have a dream which I have been holding for many years, that is after working hard for about 20 to 25 years, I can have enough money to build and manage a small bookstore or a flower shop. Besides working hard, I am able to enjoy life: to play the piano, to hike and to enjoy a two-month-long vacation every year. This may be a common dream among young Chinese students.”

There is no doubt that all of these young students have their own “China dream”. They all love China, they all love chasing their dreams. Beautiful “China Dream” requires hard work. Everyone should work hard to make their dream come true.
