The miscellaneous trees on both sides of the bank and the indescribable aquatic plants in the knee-deep water all emit a natural fragrance, entangled in the sweetness of the water vapor, intertwined and assaulting the nostrils. The setting sun in the evening brings with it bright and colorful colors, either purple or red, moving up the river, shining with an intoxicating color. The mountains on both sides, high or low, covered with miscellaneous trees, seemed to be creeping away behind them. The bamboo raft always maintained a leisurely speed, swaying forward. The water gradually became more rapid, and finally I saw another slope ahead. It seemed that there were lights flashing around me, but I soon discovered that it was not a fishing boat selling grilled fish skewers, but the increasingly intense red light of the setting sun.
