In 1933, Towkay Leong Sin Nam (梁桑南) built a residential bungalow at Cameron Highlands. The site is 1530 meters above sea level. Picture shows Sir Shenton Thomas with the owner at the front of bungalow.
The name Yi Yun Court “怡云阁”, which means “enjoying panoramic views of clouds atop the pavilion”, greets guests at the gate on the road leading to the bungalow.
The bungalow had been built with a unique architectural design. He inscribed on the building the congratulatory message “情良中心”（Love Center) given to him by the Governor of the Straits Settlements Sir Cecil Clementi Smith (马来联邦钦差大臣,海峡殖民地总督金文泰).
Picture shows the original bungalow without the added upper floor over the covered walkway linking the main building and the tower. A network of hidden underground tunnels, below the rooms' wooden floorboards in the main building and the tower, allowed escape and food stockpile for the occupants during emergencies. Leong Sin Nam was pro-China during the raging Sino-Japanese war.
The first Chefoo School was opened in China in 1881. It moved to Cameron Highlands in 1952. From 1954 to 1959, Chefoo School used the bungalow as a missionary school for children.
In 1964, the Overseas Missionary Fellowship (OMF) bought the bungalow and used it as a place of rest and spiritual renewal for members of OMF as well as local pastors and missionaries from other Christian organizations. The bungalow is now called the OMF Bungalow.
