     The Beijing government has set out to recruit thousands of university graduates to work as junior

officials in rural areas to both improve rural administration and ease the city's employment problems.

     The government plans to recruit 3,000 university graduates this year, 1,000 more than last year, to

work as assistants to village heads or Party secretaries in suburban areas.

      People interested in jobs in Beijing's rural villages and townships can submit applications to the

Beijing Municipal Personnel Bureau or online at www. Bjbys.com from February 1 through March 15.

      "We hope university graduates will seize this opportunity to use their knowledge in rural villages and

to start their careers," Sun Zhenyu, deputy director of Beijing Personnel Bureau, told Xinhua News

Agency.

      The government has promised successful candidates a monthly salary of 2,000 yuan( $ 250) in the

first year, 2,500 yuan ($ 320) the second year and 3,000 yuan ($ 385) the third year, provided their

performance is up to the required standards, Sun said.

      Wang Lina, who graduated from Beijing Union University last year, was one of the first graduates

to find work in the city's countryside. After majoring in industrial and commercial administration, Wang

served as the assistant to the village head of Ertiaojie Village in suburban Beijings Pinggu District. For

one project, Wang contacted people at the Beijing Academy of Agricultural Sciences and arranged for

the local farmers to receive training in strawberry planting. Her efforts paid off. The village had a plentiful

harvest of organic strawberries earlier this year.

      Nationwide, about 150,000 university graduates found employment in rural areas last year, according

to figures provided by the Ministry of Education.

     The ministry predicts that 4. 95 million students will graduate from universities across the country this

year, 820,000 more than last year. About 1.4 million of them are unlikely to find jobs when they graduate.

     In Beijing, a record 200,000 people are expected to graduate from university this year. Less than half

of them are expected to be offered jobs, according to the personnel bureau.
