The kindly“Chinese Fortune Grandpa”wearing Han Chineseclothing and holding a fortune bag debuted (亮相) at the Imperial Ancestral Shrine in Beijing on the day after Christmas．The final imageof the Chinese gift-giver was selected through a global design competitionagainst“Santa Claus”，according to a report by Guangming Daily．
Many Chinese cities have been filled with Christmas neon lights，Christmas songs，Christmas trees，and the images of“Santa Claus”in recent days．As a matter of fact，foreign festivals are becoming more popular than certain traditional Chinese festivals among the Chinese people，particularly the youth.“Certain traditional festivals have died out because people have forgotten their spiritual meanings，”said noted writer Feng Jicai．More and more Chinese people are beginning to exchange gifts on Valentine's Day and Christmas．However，many of them know nothing about Chinese New Year pictures or sugarcoated figurines(小糖人)，and have never heard suona music．Certain folk customs on the Dragon Boat Festival，Tomb Sweeping Day，and other traditional festivals have gradually disappeared．Under such circum-stances，even the“Chinese Fortune Grandpa”is unlikely to defeat“Santa Claus”．
However，it is not a bad thing to some extent．It constantly reminds people to restore the“true
face”of traditional festivals．China has listed traditional Tomb Sweeping Day，Dragon Boat Festival and Mid-Autumn Festival as legal holidays，which brings more paid leaves to the public，and helps to awake the public awareness of traditional festivals．
In modern society，festival is a carrier of culture and its meaning largelydepends on their understandings and usages by people．Compared with foreign festivals，traditional Chinese festivals are not inferior (次于) in cultural meanings，but lack of fashion sought by modern people．If people do not appreciate the historical culture contained by traditional festivals，and only take pleasure-seeking as the most important，the significance of traditional festivals will fade away and the inheritance (继承) of fine traditional culture will be cut off．
