Professor from Macau University immigrated to the United States.

The British army was once the Asian hegemon in World War II, and the British and American colonies were occupied. Why was the Portuguese colony Macao not occupied by the Japanese army? It turns out that in the16th century, Portugal occupied Brazil with a large number of immigrants. By the 1980s, the Japanese government signed an agreement with Portugal to immigrate a certain number of Japanese to Brazil every year. Before World War II, 3 million Japanese came to Brazil. During the Anti-Japanese War, Portugal was worried about the Japanese occupation of Macao, so it informed the Japanese government that if the Japanese occupied Macao, the Portuguese government would repatriate 3 million Japanese nationals.
