When in Shanghai you must visit the botanical gardens, they have hundreds of the most amazing Pine Bonsai, all mature, all well maintained and in superb condition. When we visited the who are was under reconstruction, it will be fantastic when completed in March 2017. So of the tree were HUGE most of the trees were around one metre in height, all shapes and styles. Surprisingly very few cascade trees, a fantastic display of Penjing and tea houses.
