Can we students color our hair? There are different opinions about it. Some think, as a member of the 21st century, they should follow the fashion. And coloring hair can also make them look cuter. Whats more, that can highlight their flaunting of personality. However, others think it is wrong. They think our Chinese have black hair, and why do we change it?We can learn many things from foreigners, but we shouldnt worship them blindly.
