Holy symbol and animal
Originally, according to legends, Lao Shu Po was merely a normal rat. This changed after the traitorous Fumeiyoshi slew his brother, the moon god Tsukiyo. The rat Lao Shu Po somehow found her way to the moon god's grave and feasted upon his divine flesh as he lay buried, absorbing some of his divine power. Tsukiyo was resurrected by the goddess Shizuru and, when they took vengeance on the vile Fumeiyoshi, Lao Shu Po was able to ascend to full blown godhood, usurping Fumeiyoshi's previous role as god of the night: she became goddess of the night, rats, and thieves.1
Church of Lao Shu Po
Lao Shu Po's worship is common throughout the Darklands of Tian Xia and her cults frequently fester beneath the city of Goka. Surprisingly, she is worshipped in the tengu nation of Kwanlai. Her other centres of worship are less surprising: dark, monster-haunted lands like Shenmen, Wanshou, and the lawless Wandering Isles of Minata.1
