This worry is fairly unnecessary. Why ? One reason lies that Christmas only affects Christians,college students and joint-venture (合资企业)workers. Another reason is that Christmas is mostly celebrated in cities. Few people in countryside show extreme interest in this exotic(带有异国情调的) festival. By contrast,the Spring Festival is the most influential traditional festival in every family.
I think,it is natural that with increasing exchanges with the West,a lot of Western holidays have been gradually introduced into China. For us Chinese we should never neglect or even discard our own traditional festivals. For centuries Chinese have observed this traditional holiday to welcome the beginning of a new year. And we will treasure the Spring Festival forever.
