What is the name of the calligraphy hanging on the wall?

There are many, such as "Heaven rewards diligence", "Benevolence carries things", "Light fragrance in the room", "lucky strike", "Purple gas comes from the east", "Elegant and harmonious in the room" and so on. A few days ago, I just booked a mountain view of "Light fragrance in the room", which is also ready to hang in the living room.
