A man uses a self-service law booth in Rugao, a county-level city in Nantong, East China's Jiangsu province, on May 7. The booth, which serves as a one-stop legal service platform, has recently been introduced to the city's industrial park. It offers professional services such as legal advice and aid, and allows people to make appointments with lawyers. More than 500 lawyers are now available for online guidance via the machine.
