A memorial service for an official who committed suicide in quake-devastated Beichuan County was held on Wednesday, while experts urged more psychological aid for officials under the pressure of the demands of reconstruction.

Feng Xiang, 33, vice director of the public affairs department, hanged himself on Monday. His 7-year-old son was killed in last year's massive earthquake in southwest China's Sichuan Province.

As per Feng wishes, his cremains were buried under a tree of Qushan Primary School where his son, Feng Hanmo, was also buried. Many officials cried at the ceremony.

Feng was the county's second official to commit suicide. Dong Yufei, 40, the agriculture commission head and disaster relief office director of Beichuan, hanged himself in October. Dong lost his 12-year-old son and other relatives in the quake.

"More than 400 county officials died in the quake, and 90 percent of the surviving officials lost their families. We are facing pressure from inner pain and the heavy job of reconstruction," said Jing Dazhong, Beichuan's county head.

Experts attributed the deaths and suicides of some quake zone officials partially to anxiety and overwork.
