The sources of funds for Liu Bei's war are mainly these three aspects: first, the local rich and those wealthy businessmen who are optimistic about Liu Bei. The second is the support of other forces who appreciate Liu Bei, that is, the gifts of the bosses who hired Liu Bei. Third, nature is the tax levied on one's own territory after establishing one's own base areas. In other words, Liu Bei also has a set of methods to obtain funds. After all, he is determined to be the boss.

Liu Bei, who made his debut for the first time, was indeed a poor man, with only the butcher Zhang Fei and the fugitive Guan Yu around him. At first, Liu Bei lacked start-up funds, but Liu Bei was descended from the royal family! This brand is a gold medal trademark. After all, businessmen in that era were rich, but their social status was low. Now there is a lonely royal child waiting for rescue. Businessmen who like gambling will definitely invest in Liu Bei in advance. After all, Lv Buwei's success is a good example.

Later, Liu Bei lived a wandering life because his official career was not smooth. However, on the one hand, Liu Bei's name is very useful, on the other hand, Liu Bei's talent is outstanding, and there are still many people who appreciate Liu Bei. For example, in Liu Zhang at that time, Liu Zhang not only sent money and military forces to Liu Bei, but also packed Yizhou for Liu Bei. It can be seen that although Liu Bei is wandering, it is also a step to expand his power.

Liu Bei, who has his own stable territory in the future, will be better prepared for military spending. After all, people on his own land have to pay their own taxes. As a result, Liu Bei gradually expanded his power and became stronger step by step, eventually becoming the overlord of Shu.
