What does the reservation in the little red book mean?

Mutual encouragement is based on good films produced by both sides, rather than treating each other as free labor. After the photographer spent a lot of money on equipment learning in the early stage, he had to cook a proper meal. Models also spend a lot of energy in the shooting process, and constantly adjusting their state for a long time will make them tired and doubt their lives. Therefore, it is very important for both sides to understand and respect each other.
