Sichuan
In Sichuan mythology, Tubo is the first Emperor of Ghost (鬼帝). In ancient times Sichuan Basin was resided by two different ethnic groups, Ba people and Shu people. With the continuous exchanges in terms of religion, culture and ideologies, some common beliefs and identities were formed and shared. And Tubo is one of such common gods worshiped by both ethinic groups, as the first Emperor of Ghost. Some historians argue that Tubo was a tribe leader of the Ba peple, because in Eastern Zhou dynasty, Youdu where Tubo lives was the capital of Ba (state), while the some tribes of the Ba people were called Gui Zu (鬼族, Ghost clan).

In Eastern Zhou, people of Chu made sculptures of Tubo, and put them into graves as Zhen Mu Shou (镇墓兽), which are monster sculptures to soothe the soul of the deceased while protecting it from wandering ghost. The sculptures were usually made of wood and brass, and antlers were often used. Most such sculptures are found in Chu graves belong to scholar-bureaucrat class who followed Wu Shamanism (巫觋). They usually believe that Zhen Mu Shou could bring their spirit to the Tian Jie and thus become immortal. Although the faces of the existing monster sculptures are mostly obscure, other characteristics such as sharp horns, curved body, bulging eyes, ghostly expression, and close link to the underworld all bear remarkable similarity to descriptions of Tubo in historical texts.
