14 Chinese are being tried on charges of organizing a 3-day sexual party in Zhuhai, China, involving about 900 people. The defendants include two hotel employees and 12 Chinese "mami" (Madams).
About 400 Japanese businessmen and 500 Chinese "hostesses" took part in the event, which marked the anniversary of a Japanese attack on China, one that many Chinese point to as the start of the World War II Japanese invasion and occupation.
All of this has caused an international incident. The Chinese filed an official complaint with the Japanese government. To protect privacy, this trial will be held in closed session. Source
