I noticed a real effort being made to repair the beams and posts that weren't too damaged. The damage was caused by rot over the centuries and by wood eating insects.
At the same time as these repairs were being made, the Buddha figures from the hall were being restored. I got to see a lady working on Buddha sitting on a lotus. She was doing painstaking work similar to what I've seen on television of museum art restoration work. I must say she was doing beautiful work bringing the Buddha sculpture to a spectacular state. Unfortunately, photos were not allowed in that area.
