He once again spoke about his travels. He said that whenever he sets out, he carries only a lunch box, a spoon, a pair of chopsticks, and a water bottle, along with a bar of soap for washing clothes, face, and body. He tries to produce as little waste as possible, and if there is any, he always cleans it up and takes it away. He never writes travel notes, because some places remain in a very pristine state, and he does not want his presence to leave any impact. In such places, he tries to make it seem as if he had almost never been there.
At dinner, the cured pork at home was exceptionally delicious, and he praised it highly. My mother suggested he take some back with him, and he was visibly tempted, saying he would love to bring some for his mother and wife, since restaurants in big cities rarely offer such flavors.

晚饭时，家里的腊肉味道极好，他吃得连连称赞。母亲提议让他带一些回去，他也明显心动，说很想带回去给母亲和妻子尝尝，因为城市里的餐厅很难吃到这样的味道。但经过一番思考，他还是选择放弃。他说接下来的旅程还很长，路上总会遇到更好的风景与食物，再多的口袋也装不下，因此必须学会轻装前行，舍弃不必要的负担。
夜晚，我们在院子里喝茶赏月，话语不多，只是静静对坐了很久。第二天他便告辞离开，后来在短信中告诉我，那一夜苍山幽远，月色清澈，让他十分感动。
