What climate type does Guangzhou belong to (an answer to understanding climate types)

It belongs to subtropical monsoon climate, but due to the development of Guangzhou city and the expansion of urban area, there is a tropical monsoon climate at the southernmost tip of the Tropic of Cancer;

As the global temperature rises, the weather in Guangzhou begins to approach the tropical monsoon climate.

However, there is no such thing as a tropical maritime climate in South Asia.

In China, except Hainan Province, which is tropical, it is subtropical to the south of 30 degrees north latitude, and the Qinling Mountains and Huaihe River are the boundaries, separating the warm temperate zone from the subtropical zone. There is no rule that 30 degrees north latitude must be the dividing line.

On the other hand, Guangzhou belongs to the subtropical monsoon climate zone.
