Where is Nanyang that China said?

China's "Nanyang" was a name for Southeast Asia in the Ming and Qing Dynasties, and it was a concept centered on China.

Nanyang includes Malay Archipelago, Philippine Archipelago and Indonesian Archipelago, as well as the coastal areas of Indo-China Peninsula and Malay Peninsula.

The concept of Nanyang corresponds to the West Sea, the East China Sea and the North Sea. The west refers to the Indian Ocean area west of the Straits of Malacca, including Europe or beyond. The Qing dynasty once referred to European and American countries. The east refers to Japan in particular. In ancient China, the Han nationality began to emigrate to Nanyang. During the Ming Dynasty and after its demise, a large number of Han immigrants flooded into this area to make a living and settle down, which was called "going to Nanyang" in history.
