The Chinese Festival Spring Festival probably is the grandest,and the happiest festival in all of Chinese traditional festivals.According to the Chinese traditional calendar NongLi(农历),it's the first day of a year.So There're lots of ubiquitous customs in China to pass through or celebrate this beginning of a year,meanwhile differences are among them.And we also have a plenty of fastidiousness for pleasing deities in folklore,showing respect to elders in family and making yourself advance to a hopeful,abundant gathering and luxuriant fortunate new year. Anyway,a fact that few people have ever learnt of is,the beginning of a year was not always the same time from ancient age.First Chinese NongLi calendar was arose in Xia(夏)dynasty,which is the first dynasty of China that we could ever knew.This dynasty is cause of why the Nongli calendar we use in today is also called Xiali(which means Xia's calendar).It ruled that MengXiYue(孟喜月) people should start a new year,and that was to say the month of January determined to be the first month of a year. Then the time past,a tribe called Shang(商)replaced Xia(夏)'s position and built their own dynasty,which has brought a little different calendar called YinLi(殷历).YinLi considered the month December as the first month of a year.The dynasty after Shang was Zhou(周) Dynasty.In this eight-hundred-years dynasty China intended towards disunity and turbulence,when vassals' officially calendar even could be much as 5 kinds of.However the calendar approved by the royal hold November as beginning of a year, until the Qin(秦)dynasty finally replaced royal and unified China under one rule and one calendar again,which October has been legalized to be the first month. Remainingly,regions have their own provincial ways to calculate date.So which day the exact new year day would be still has not been certained.Chaos had been terminated in the great HanWuDi(汉武帝)'s era, a significant period of Han(汉)dynasty.A reformation package had been put into effect in not only authority and millitary, but also top to bottom of this country, to make it more stronger and to be harder defeated. HanWuDi,he who the great emperor changed calendar back to XiaLi(夏历) again and defined which day should the new year day be clearly.Last then,this day he stipulated is also called ChunJie(the Spring Festival)and be used thousands years continuing, celebrated in Japan until 1880s, and China, South ＆ North Korea, Vietnam until today.
