Miscellaneous trees on both sides of the river and nameless aquatic plants in knee-deep water all exude a natural fragrance, which is wrapped around the nose by the sweetness of water vapor. Evening sunset wrapped in a touch of bright colors, or purple or red, wandering on this river, shining with intoxicating colors. The rolling hills on both sides, high or low, are covered with miscellaneous trees and crawling behind them. The bamboo raft has kept a moderate speed and staggered forward. The current was rushing gradually, and finally I saw another slope ahead. There seemed to be lights flashing around, but I soon discovered that it was not a fishing boat selling grilled fish skewers, but the increasingly red light of the sunset was shining.
