Venerable Wai Yim was appointed as the Abbot of Lian Shan Shuang Lin Monastery in 2003.
Putting on his robe at the age of 21, he went to Hong Kong to pursue his first and second degrees. Upon his immediate return to Singapore after completion of study, the Trustees of Lian Shan Shuang Lin Monastery invited him to serve as the Chief Executive (Jianyuan) of the monastic order in 1987.
In 1991, it was confirmed that the timber structures of the Shuang Lin National Monument were badly infested by termites, the Trustees again decided to entrust the challenge to him. As Chairman of the Preservation and Conservation Committee of Shuang Lin Monastery, he led his able team to formulate master plan for Shuang Lin Restoration with a long term goal and to raise fund from all sectors and the community at large. Phase 1 to phase 5 of the Restoration project took more than 10 year and the chapter was beautifully closed in 2002.
