Although "Guangdong" is a homonym of "Guangdong", it has been proved that the word "Guangdong" has been used to describe Guangdong in the Tang Dynasty, which can better explain the social and economic situation in ancient times. In ancient China, Lingnan was really a "barbarian" land. When officials are demoted and felons are exiled, the court will choose Lingnan or the frontier, which shows that Guangdong's economy was relatively backward in ancient times (before the Yuan Dynasty) (of course, the economy is very developed now, so the wind and water turn around). ) "Guangdong" belongs to the combination of knowing characters and pictographic characters. The upper part of the word "Guangdong" can be regarded as the lower part of the rice warehouse, and the "deficit" is removed! But generally speaking, Cantonese characters can reflect the economic status of ancient Lingnan in China, which is called "rice shortage".
