元宵節的由來英文介紹


  The Lantern Festival falls on the 15th day of the 1st lunar month, usually in February or March in the Gregorian calendar. As early as the Western Han Dynasty (206 BC-AD 25), it had become a festival with great significance. This day's important activity is watching lanterns. Throughout the Han Dynasty (206 BC-AD 220), Buddhism flourished in China. One emperor heard that Buddhist monks would watch sarira, or remains from the cremation of Buddha's body, and light lanterns to worship Buddha on the 15th day of the 1st lunar month, so he ordered to light lanterns in the imperial palace and temples to show respect to Buddha on this day. Later, the Buddhist rite developed into a grand festival among common people and its influence expanded from the Central Plains to the whole of China.
  
  每年農曆的正月十五日，春節剛過，迎來的就是中國的傳統節日--元宵節。元宵節主要的活動就是看燈。東漢明帝時期，明帝提倡佛教，聽說佛教有正月十五日僧人觀佛舍利，點燈敬佛的做法，就命令這一天夜晚在皇宮和寺廟裡點燈敬佛，令士族庶民都掛燈。以後這種佛教禮儀節日逐漸形成民間盛大的節日。該節經歷了由宮廷到民間，由中原到全國的發展過程。
