Mother and wife fall into the water at the same time, who should be saved first?

Save your wife first. Even if the mother dies, she will be disappointed and will figure it out in the underworld, thinking that her son is great and his son is doing the right thing. Because your wife is the child of other people's parents, if you don't save your wife first, others will scold you for looking down on yourself, feeling guilty and sorry for more people.
