元宵节有什么由来和习俗？
元宵节的由来英文介绍：
Lantem Festival The 15th day of the 1st lunar month.
The 15th day of the 1st lunar month is the Chinese Lantern Festival because the first lunar month is called yuan-month and in the ancient times people called night Xiao. The 15th day is the first night to see a full moon. So the day is also called Yuan Xiao Festival in China.
According to the Chinese tradition, at the very beginning of a new year, when there is a bright full moon hanging in the sky, there should be thousands of colorful lanterns hung out for people to appreciate. At this time, people will try to solve the puzzles on the lanterns and eat yuanxiao (glutinous rice ball) and get all their families united in the joyful atmosphere.
译文：
元宵节正月十五吃元宵的的习俗由来已久,元宵也叫汤圆”、“圆子”。据说元宵象征团圆,吃元宵意味新的一年合家幸福、万事如意。
元宵节闹花灯的习俗起源于道教的“三元说”;正月十五日为上元节,七月十五日为中元节,十月十五日为下元节。主管上、中、下三元的分别为天、地、人三官,天官喜乐,故上元节要燃灯。元宵节的节期与节俗活动,是随历史的发展而延长、扩展的。
就节期长短而言,到唐代已为三天,宋代则长达五天,明代更是自初八点灯,一直到正月十七的夜里才落灯,整整十天。与春节相接,白昼为市,热闹非凡,夜间燃灯,蔚为壮观。特别是那精巧、多彩的灯火,更使其成为春节期间娱乐活动的高潮。至清代,又增加了舞龙、舞狮跑旱船、踩高跷、扭秧歌等百戏内容,只是节期缩短为四到五天。
