    • Female Chinese space pioneers?
      CHINA plans to recruit(招募) women astronauts thanks to the lobbying(游说) of the leading women’s organization. Gu Xiulian, president of the All-China Women’s Federation(ACWF) (全国妇联), said on Saturday that she put forward a proposal that women be trained for space missions after the manned space flight last October. And it was accepted by the central authorities, local media reported. But the plan to recruit female astronauts has yet to be worked out, according to sources close to the astronaut-training programme.
      Beijing needs mental health care
      MORE than 1,000 people committed suicide(自杀) in Beijing last year, and experts have been encouraging the capital to set up a mental health care system as soon as possible, local media reported last week. About 20 percent of the people of Beijing live in unhealthy conditions, with 3 percent of these suffering from affective disorder and 5 percent reporting symptoms of depression, according to the Beijing Mental Health Service Center.
      No need to fear your licence plate
      CAR licence plates in Shenzhen and Guangzhou, Guangdong Province, will not have the number “four” from this month on ---a move that has led to heated discussion among officials, schools and residents. The word for “four” sounds like “death” in Cantonese. The number has been cleared away from the computer data banks that generate the six-digit licence numbers for local cars. Some say that, for the first time, a public agency service has considered local customs and bans. Others worry it will encourage superstitious(迷信的) beliefs.
