The mulberry zhuzongbao, known as the small Potala Palace in Shigatse, is an outstanding representative work of Tibetan castle architecture. It is 280 meters long and 92 meters high, and covers the entire top of the sun, which is both tall and elegant and beautiful. Only because of the wooden stone structure of the palace castle, due to the erosion of the years and the destruction of the "cultural revolution" period gradually destroyed, only some of the broken walls of the city platform left, can only see the glory of its past.
