The sovereignty of Hong Kong went back to China in 1997 and Macau went back to China in 1999, different political, economic , social and law systems existed in Taiwan, Hong Kong, Macau and Mainland China.The Chinese jurists can learn the lesson from the unitary conflicts law between East & West Germany and establish a perfect model of distinctive feature of Chinese conflicts law.The writer analyzes the conflicts law among Taiwan, Hong Kong, Macau and Mainland China and put forward a legislative draft about ”the application of civil affairs law between Taiwan, Hong Kong, Macau and Mainland China.” I hope this legislative draft can be provided as a reference for juridical and scholarly concerned departments.
