Traveling to Tibet, this stop came to Shuanghu County, after settling in the hotel at night, we came out to find food, the roads of this county town are being repaired, surrounded everywhere, or dug. The restaurants here are basically no guests, I really don't know how their business will continue. I chose one of them and asked them what specialties they had. The waitress asked us to choose by ourselves and refused to say anything delicious. I ordered sweet and sour ribs, and the meat of the ribs was black. As soon as I ate it, I knew that the ribs were frozen in the refrigerator for a long time. The thawing was not completely cooked. The sweet and sour taste is OK, not very sour. The price of food is medium for Tibetan areas.
