3月4日，王先生发文称，3日下午，其母亲在吉林长白山优山溪谷景区玩漂流时，船在终点处侧翻，导致母亲被水冲走失联，王先生质疑为何终点没有安全网，仅设置一根绳索。并且出发前工作人员一直催促大家快点穿救生衣“救生衣只需要扣一个扣子就行了”

之后王先生再次发文称，母亲已经找到人已经去世，母亲从水底打捞上来时，救生衣已不在身上。

On March 4th, Mr. Wang posted that on the afternoon of March 3rd, his mother went missing after being swept away while rafting at the You Shan Xi Gu scenic area of Changbai Mountain, Jilin. The boat capsized at the endpoint, and Mr. Wang questioned why there was no safety net in place, only a single rope. He also mentioned that before departure, staff kept urging everyone to quickly put on life jackets, saying, "You only need to fasten one buckle."

Later, Mr. Wang posted again, stating that his mother had been found but had unfortunately passed away. When her body was retrieved from the water, the life jacket was no longer on her.
