Heiquan Reservoir, Xining's water source, Xining people's source of life. Quiet place. Driving on the side roads was the only way to get there. The weather was very cloudy on the day of the trip. It looked a little less scenic. The whole car and house were buried in the debris flow that happened during the flooding a few days ago. This route passes through the 10,000 Mu rapeseed flowering field in Menyuan. It was only in mid-August that the rapeseed flowering had disappeared. The most beautiful season in Menyuan is from the end of July to the beginning of August. The golden rapeseed blossoms are very beautiful.
