The Cross-Strait between Taiwan Area and Mainland Area has been ruled separately for over five decades since 1949 after losing the Chinese mainland as a result of the Chinese Civil War (1947), the ROC government under the Kuomingtang (KMT) relocated to Taiwan. After long time of separated ruling of Cross-Strait, there are major differences in political system, government decision, legal system and style of social society. And also the end of martial law was declared by the government in July 15 of 1987. In the same year of November 2, it was also allowed visits to relatives on the mainland. In 1992, the government allowed Chinese spouses to settle down in Taiwan. And Taiwan has implemented the enforcement rules for the Act Governing relations between peoples of the Taiwan area and the Mainland area and its articles which will be the legal base among the people of Taiwan and mainland China for their social interactions. Prior to Taiwan government allowing its nationals to travel to China, people of China area have been smuggling to Taiwan to work and prostitute for a long time. Early, people of China area who smuggled to Taiwan working and prostitution were arranged by ¡§snakeheads¡¨ or people smugglers, using the fishing boats by sea route to enter Taiwan, then prostituted agency or middle man will control and arrange them to do work and prostitute. Because of the high risk that is involved in smuggling, Chinese nationals seem to favor other means of entering the country. Since the government opened private exchanges between the two sides of Taiwan Strait, based on the ¡§Regulations for Permitting the Spouse Residency; Long Duration of Stay, and Permanent Residence of Mainland People in the Taiwan Area¡¨, the spouse who is from Mainland Area applying for family reunion or family visit is quite easy to get a permit, that provides a great opportunity for the snakeheads. The snakeheads and people smugglers are using the legal reason to help the People of Mainland Area entering Taiwan Area illegally. It also creates corrupted police problems and affects seriously on the public security and safety of the Country.
