Introduction to Chao Phraya River: The full Thai name of Chao Phraya River is "Chao Phraya Chao Phraya", which is the real name of the river and means "Mother of Rivers". The total length of the Chao Phraya River is 1,352 kilometers. Its upper source is formed by the confluence of two larger rivers from north to south, the Bin River and the Nang River. After the two rivers merged in Nakhon Sawan, it was called the Chao Phraya River and runs from north to south. The entire territory of Thailand, accounting for about 1/3 of the country's area, is one of the important rivers on the Indochina Peninsula.
