We played the wrong route. I heard that to play Erhai, we had better take a bus to Shuanglang first, rent a car in Shuanglang, and play along the coast slowly. Unfortunately, we don't know. Starting from Caicun Wharf, we can hardly see the sea when we ride along the coast. There is still a section of road repaired along the coast. Next time I have a chance to play again.
