Ming troops and generals strictly followed this policy, and they worked very very well ! They confisticated most of Vietnamese books at that time (to make the Vietnamese be illiterate and forget their ancestor’s history), destroyed nearly all every temples in the area of North Vietnam today (For example, The Four Great Treasures of Annam, 安南四大器, or An Nam Tứ Đại Khí (Báo Thiên Tower, Phổ Minh Caldron, Quy Điền Bell & Buddha Statues of Quỳnh Lâm Temple), were subsequently demolished.

Moreover, to wipe out and destroy all everything in Vietnam effectively, economic exploitation (in fact ECONOMIC GENOCIDE) policies were promulgated and strongly emphasized by Ming Emperor Yongle as well as his henchmen and generals. The Official Records of Ming dynasty, or the Ming shi lu, “proudly” announced the “achievements”: As a result of the war, 13.6 million piculs of grain were obtained, 230,590 elephants, horses and cattle, 8,677 ships, and 2.5 million military weapons were “confiscated” from Vietnam.

Twenty years of bloody and devasting war in Annam (1407–1427) also costed the Ming Dynasty heavy prices: hundred thousands of their troops died in vain in Annam, especially during decisive battles of 1408 (Battle of Bô Cô), 1426 (Battle of Tốt Động - Chúc Động, 崒洞祝洞之戰) & 1427 (Battle of Chi Lăng - Xương Giang, 支棱昌江之戰). The success of Lam Sơn Uprising (起義藍山) finally ended the Fourth Chinese Domination of Vietnam and subsequently led to the establishment of one of the most powerful Vietnamese dynasties - the LÊ DYNASTY.
