Does anyone know why Guan Gong is respected in Shunde's factory?

"Wu Caishen"-Guan Shengdi Guan Yunchang.

It is said that Guan Yunchang managed the military horse post station and was good at counting, which made his invention increasingly thin and stressed credit and loyalty, so he was worshipped by merchants. Generally speaking, businessmen regard Guan Gong as their patron saint, and Guan Gong is also regarded as the god of wealth.

Businessmen who believe in Guan Di Sheng Jun will sacrifice, set off firecrackers and burn gold paper for Guan Gong on the fifth day of the first month, and ask Guan Di Sheng Jun to bless a prosperous year.
