In 1982, a toy factory in Shenzhen invested by a Hong Kong company came to Shantou City to recruit workers. Weng Chunxian, a high-school graduate, took the opportunity and became a worker in the production line of the Kaida Toy Company in the Shekou Industrial Zone. During her days in Shekou, she continued to study in her spare time, earned herself a home, and at the same time, improved the living conditions of herself and her family. Then she left the company, went to university, entered the glass industry and began a management career until her retirement this year. About half of Weng's fellow migrant workers who came to Shenzhen together are still in the city, and most of them are making a good living. When China established the Shenzhen Special Economic Zone in 1980, its population was less than 30,000. Forty years later, it has developed into the biggest immigrant city in China housing 13 million with its GDP hitting 2.69 trillion yuan (about 389.4 billion U.S. dollars). (Xinhua)
