“谷雨”，有一个美丽的传说，相传以前老百姓每年要将绝大部分谷子交给玉皇大帝，留下的仅够一天吃一餐。一年大旱，谷子绝产，玉皇不见上交谷子，龙颜大怒，派大臣“天牛”下凡传旨“人间一日一餐改三日一餐”。
天牛来到人间，对百姓深表同情，擅改圣旨为“人间一日一餐改一日三餐”，只字不提纳粮之事，从此人间改为一日三餐。天牛上天禀报：“臣已传旨，但人间大灾，粮食失收，无粮可交。”次年春天，天牛假传圣旨之事泄漏，玉皇以欺君之罪贬天牛管理南天门粮仓，派天兵天将到人间抢走所有口粮和种子。正值播种插秧之际，百姓仰天痛哭。
天牛深感痛心，在一个春雨绵绵的日子，他偷偷打开粮仓，把谷子随雨撒下人间，百姓奔走相告“天下谷雨啦”，纷纷跑到田野去耕种。
触犯天条的天牛，被玉帝罚下人间投胎为牛，永世耕种土地。后来，人们把这天叫做“谷雨”，作为“牛神”——天牛的生日，民间这天农家不役使耕牛，还喂精饲料，有的甚至煮甜酒冲蛋喂之，以示谢意。
