When the family fortunate declined, the garden fell into ruins but it was eventually purchased and restored by the government in 1973, and opened to the public in 1974, according to the tourist brochure. When we visited the garden, we saw many local residents, mainly elderly people, were exercising in the nice garden.
The main building in the garden is now a pavilion for for arts & craft exhibition and other cultural activities. This picture is the back of the pavilion with two balconies over the pond.
