In the Three Kingdoms, what did Liu Bei do for a living?

Liu Bei (161-223) was the son of Liu Hong after Liu Sheng, King Jing of Zhongshan in the Western Han Dynasty. His father died in his early years and he made a living by selling shoes and weaving mats.

That is, selling shoes and woven straw mats. Selling shoes does not necessarily mean only buying straw sandals. He should also sell other cloth shoes and boots, because there is no specific explanation that he only sells straw sandals. He just said that he was a shoe seller

Later he became Yuzhou and was called Liu Yuzhou. Later he met Zhuge Liang and became the emperor for one third of the world
