The number of lawyers in China has risen from a few thousand to 230,000 in the past 30 years. One of these is Bian Guanghua. In the city of Zibo, in the eastern province of Shandong, Bian takes cases that many official lawyers won't or can't take. However, in many places, licensed lawyers remain scarce. As a result, unofficial "citizen representatives", with little or no legal training, often fill the gap.
