In the beginning of the Eastern Han Dynasty (25–220), Emperor

汉明帝 was an advocate of Buddhism. He heard that some monks lit lanterns in the temples to show respect to Buddha on the fifteenth day of the first lunar month.
Therefore he ordered that all the temples, households, and royal palaces should light lanterns on that evening.
This Buddhist custom gradually became a grand festival among the people.
