The bedroom door faces south, the south wall is the toilet sink wall and the north is the window. How should I put the bed?

If you want to be comfortable, put it in the sun. If you say feng shui, you have to invite people to see it! Generally, the bedside should be against the wall, not against the toilet or door. There is no mirror at the end of the bed. Especially not according to the bed. Or next to the window. There are many taboos. Speaking of feng shui, you can only find a reliable look. In fact, anything will do as long as you are comfortable.
