I'm preparing a PhD application, and I would like to have a bucket list of ideas for researching on this subject. After reviewing literature, I realized this topic is widely investigated. So far, I came up with the following ideas:

Comparative profile of skilled workers v.s non skill workers migrating to to Southeast Asia 1800-2000.

Cultural representation of Chinese influence on governments of Southeast Asian countries during the fourth wave of migration.

Talent hunting of Chinese nationals. Singapore’s policy for international students and its effects.

Religion as a factor of mobilization: the case of Chinese Hui Muslim students in Malaysia.

Traces of Chinese identity. Analysis for second and third generations of Chinese descendants in South East Asia.

Returning to the roots. The case of Southeast Asian Chinese offspring returning to China in the last decade.

Current linkages of Chinese overseas with their relatives in Continental China.

Behavior of remittances during the modern emigration of Chinese to Southeast Asia.

If you are an expert, please let me know your opinion on these subjects and give me more ideas. Thanks!
