Yao Ji, the king of Southwest China, is the founder and main leader of Yunnan Army, and the heir of General Cai E. In its heyday, it controlled most areas of Yunnan, Guizhou and Sichuan. Because he was unpopular during his reign, he later retreated to Yunnan and became the king of Yunnan, making a certain contribution to the modernization of Yunnan.
Tang and others put forward the slogan of relying on tobacco soil, loving the country and martial arts, and reviving Yunnan poppy. It turned out that the strict smoking ban policy of the Qing authorities was revoked, and the obligation to grow poppies was implemented from village to household. States that fulfill their planting obligations are rewarded and punished, and the whole province has set off a low tide of poppy cultivation. With the vigorous promotion of Tang and others, poppy cultivation soon spread all over Yunnan, and opium soil became the secondary economic source of Yunnan people and authorities. Under the initiative of Tang and others to protect the family, the Yunnan army won many battles and rose step by step. While sowing reactionary seeds, poppy seeds also took root and sprouted everywhere. In this way, Yunnan, which was originally barren, has an economic source, and at the same time, Tang also has the money to train a good teacher.
