I have run almost all Yunnan restaurants in Beijing, just want to eat a bowl of pea powder and roll powder, but I can't find it. On March 2, I finally got my wish. After visiting the Tengchong Beihai Wetland, I asked for a small bowl of pea powder and roll powder mixed in the Radisson Blu Powder Store. The taste was really a taste of childhood, really authentic and delicious.
