根据民间传说，农历二月初二是长官云雨的龙王抬头之日。过了龙抬头这天，雨水充沛，所以这天被称为春龙界。中国北方的农民深信龙抬头后雨水充足这事，到时粮仓无论大小都会装满粮食。每当春龙节到来，中国北方都会舞龙，大部分地区在这天早晨家家户户打着灯笼到井边或河边挑水。回到家里便点灯、烧香、上供，理发（有习俗正月理发死舅舅）。旧时，人们把这种仪式叫做引田龙。这一天，家家户户还要吃面条、炸油糕、爆玉米花（比作为挑龙头、吃龙胆、金豆开花，龙王升天，兴云布雨，五谷丰登），以示吉庆。

A popular fairy tale in the north of China can tell the origin of the day. When Wu Zetian, the empress, in the Tang Dynasty came into power, the Heaven God was so angry that he ordered the dragon kings to stop raining for 3 years. Soon after this, the dragon king who was in charge of the heaven river heard the bitter cries from the folk, saw many people starve to death. He was afraid that there would be no life in no time. Then he went against the Heaven Gods order and gave the folk a heavy rain. Because of this, the dragon king was thrown into the folk world by the Heaven God and pressed under a large mountain.

北方庆春龙节还因为另外一个传说。相传唐朝，武则天登位做了皇帝，玉帝大怒，命令龙王三年之内不能降雨。但龙王日日听闻百姓哭泣，见无数百姓音饥饿而死，他担心很快地球上就没有生命了。于是他违背玉帝旨意，给老百姓降了一场大雨。玉帝得知后，将司掌天河的玉龙打下天宫，压在一座大山下面。（山下还立了一块碑，上面写道：龙王降雨犯天规，当受人间千秋罪。要想重登灵霄阁，除非金豆开花时。）
