What does Tim Cang Day mean?

In my hometown, it was the "Tiancang Day" on the 19th day of the first lunar month, which was a successful conclusion.

"Tiancang Day" is also called "Tiancang Day" and "Tiancang Day". According to legend, in the Western Han Dynasty, Yuyan Chun was framed as a granary official, sentenced to death and imprisoned, and was pardoned by his daughter's complaint. He is upright and admired by later generations. In order to commemorate him, it gradually evolved into "Tim Cang Day".

However, the time varies from place to place. From the 20th to 25th of the first month, my hometown designated January19th as "adding positions day". On this day, every household should steam steamed bread in the shape of a pocket or an ingot with flour, light lamps and burn incense at night, worship the official of jiacang, and shout loudly "jiacang, jiacang, go home and drink sour soup", mainly to pray for a bumper harvest and hope to live a rich life.
