I went on New Year's Day holiday in 16 years, when plum blossoms were in full bloom. The temperature of Yunutan is around 15 degrees Celsius all year round. Even in winter when the mountains are closed by heavy snow, the trees around Yunutan remain green. Looking down from a high place, the pool is blue and beautiful. According to the advice of the sweeping aunt, it is feasible to walk down the stairs in a day, and it is interesting to drill holes.
