The next morning, the two of them discuss Mr. Li's recent social media posts. Mr. Liu has been very active on Weibo, and he's become very popular in the process. He used to post travel photos that were not popular at the time, but when he began to post science stuff, it became very popular. He also used to build a wooden boat and let it travel downstream on the Grand Canal. He asked his followers to donate money every time the boat reached the two hundred-kilometer mark. The boat is still missing, but the two agree that it's very meaningful to him. He says that he was looking through his feed the other day and saw that the charity project had been going on for six months. He's curious about the missing boat, but he doesn't know what happened to it because he hasn't looked for it. He wants to know if he can help with it, but his stomach is acting weird, so he says he'll take him to the hospital.
