With the development of society and economy, education has gradually become more internationalized, and the group of international students in my country has become increasingly large. The proportion of international students studying in Thailand continues to increase. There are huge cultural differences and language barriers between Thailand and China, which often make it difficult for Chinese students to quickly adapt to the new environment. Cross-cultural adaptation causes Chinese students studying in Thailand to face huge challenges in life, study and other aspects. Cross-cultural adaptation problems arise when people enter different cultural environments. Some of these problems come from the external environment, and some come from the cross-cultural people themselves. Generally speaking, cross-cultural people will go through several stages such as stress, adaptation, and advancement, and finally complete their acceptance of the new cultural environment. Whether cross-cultural adaptation goes smoothly or not depends on both external and internal factors. Understanding these influencing factors can help people better deal with the problems encountered in the process of cross-cultural adaptation.
