Introduction to the Taihu Stone with the word "Shou": In the courtyard of the old house, there is a Taihu stone about 4 meters high, which can be said to be the treasure of the Hu family's house. This stone is naturally made and looks very much like the Chinese character longevity. It was a gift given to his mother by Hu Xueyan on her 80th birthday.
