There are Borobudur in Indonesia and Angkor Wat in Cambodia in Southeast Asia, which are known as the four wonders of the ancient East.
There are many historical sites in Southeast Asian countries, such as the "Javanese Ape" site in Indonesia and the "Peace Culture" and "Dongshan Culture" sites in Vietnam. In addition, all countries in Southeast Asia belong to multi-ethnic countries, and the customs and ethnic characteristics handed down from generation to generation have increased the great interest of tourists. For example, various ethnic groups in Thailand have colorful festivals, such as Songkran Festival, loi krathong and Elephant Festival, as well as world-famous classical dances and folk dances, with unique Thai boxing, elephant racing, cockfighting and fish watching.
