I don't think it's worthwhile to sell the house in Suzhou. After all, Suzhou's real estate has not yet reached its limit, and there is still room for appreciation. If your house is the planning site of future subway and intercity railway, there is more room for appreciation. However, if the house in Shanghai is bought in central China and Inner Mongolia, the price is basically around 2W, which has reached the limit and there is not much room for appreciation. /kloc-two rooms (80 square meters) of about 0/00w can only be bought near or outside the outer ring.
After all, you have a house in Shanghai, and it will be more economical to sell it when the house in Suzhou rises to a satisfactory price.
