Washing the face in wudhu

Q:

1. When the boundaries of the face are mentioned in the books of Fiqh, are the boundaries included in the washing i.e. is the bottom of the chin included and must be washed?

2. If someone came and said to you, "I can’t see the bottom part of my nose (just above the moustache) so must it be washed? What would you say to him when telling him about the definition of the face?
