The Nan Lian Garden is situated at Diamond Hill and is easy accessible by the MTR. Right beside is the Chi Lin Nunnery and you can do both on a half day trip.
The garden is built in the Tang Dynasty style (618 AD to 907 AD). Hills, rocks, ponds, plants and trees are arranged according to the Tang style and rules. It is a tranquil place surrounded by skyscrapers and roads.
The Chi Lin Nunnery is a Buddhist temple complex and also built in the Tang Dynasty style. It was built without any iron nails and uses special interlocking systems cut into the wood to hold everything in place.
There is no entry fee and a must-see if you visit Hong Kong.
The Jade Buddha Temple in Shanghai is a good place to go. In the temples is always a nice and calm atmosphere which sometimes is a needed contrast to the busy life in the city. The temple holds two jade Buddha statues. They are made of porcelain, one is a Sitting Buddha and the other is a recumbent Buddha.
The Lama Temple in Beijing is the largest Buddhist temple in China. There are five large halls and you should spend at least an hour in the temple. In the hall of Ten Thousand Happinesses you can find an amazingly tall (18m) statue of the Maitreya Buddha. It is carved from a single piece of White Sandalwood. This statue is one of three artworks in the temple that were included into the Guinness Book of Records in 1993.
