Chu Quyen Temple , which is commonly known as Chang Temple ,in Hanoi 's Ba Vi district was primarily built with wood by the endof 17th century.
The temple was recognised as anational historic heritage site in 1962. Restoration on the temple beganin 2005 and was completed earlier this year.
Various modern techniques were used to remove mould from the wooden pillars, Vinh said.
"While overseeing the restoration work, I noticed that we didn't haveenough professional restorers," said Vinh. "We cannot restore a relic ina rush without taking the proper precautions. There are only a fewexperts who can handle such a task."
Vinh said thecountry needs to begin training more restoration workers, who areexperts in architecture, construction, culture and history.
Deputy Minister of Culture Tran Chien Thang said that the projectshould serve as the standard that later restoration projects shouldemulate./.
