The Saihanba Dam is 470 kilometers north of Beijing, and you know that it may be because of the spirit of the Saihanba Dam. Three generations of people introduced here are trying to prevent wind and fix sand. Most of the Saihan Dam in the documentary is full of flowers and lush jungles in summer. I would like to share with you the winter scenery. Because of the geographical location, most of the winter temperatures on the dam are around - 20 - 30 days, and snow cover from December to March. In winter, neither Saihan Dam nor the adjacent Ulan Butong sells tickets. So it's worth it. There are many farmyards in Saihanba, where people live. It's very warm for collective heating. If not for holidays, most of them are 1001. I can introduce you by confidence. The following pictures show Saihan Dam and Ulanbu tradition. It's still beautiful. Friends must be ready for winter equipment if they come here in winter. And the fruit heater is very dry, and there is no place to sell vegetables and fruits. It's not cold outside.
