He came to Shenzhen alone, but now shares a rented flat with 12 other migrant workers. It had been easy to find work, and he said he had a permit. He had been in Shenzhen three months, and did not know how long he would stay.
This man is part of China's huge rural floating population. No one is sure how many people leave their homes in search of jobs, but estimates run to around 90 million. It is a welcome freedom that did not exist before the reforms, because strict local party control and the need for food coupons used to keep people tied to their local work units. But it is also symptomatic of serious underemployment and poverty in inland rural areas which have fallen behind as coastal areas have grown rich.
