Suggestions to deal with this situation include in-depth understanding of the reasons, frank communication, setting clear goals and reward mechanisms.

1, find out why: find out why my daughter smokes. Whether because of curiosity and imitating peers, or in order to relieve stress and seek excitement, understanding the reasons will help to find a more accurate solution to the problem.

2. Frank communication: communicate frankly with your daughter and let her know the harm of smoking, including physical health, mental health and social image. We should also listen to our daughter's thoughts and feelings, try to understand her situation and avoid accusations and criticisms.

3. Set clear goals and reward mechanisms: Set smoking cessation goals with your daughter and make specific action plans. In order to encourage daughters to quit smoking, we can set up a reward mechanism, such as giving appropriate rewards after reaching a certain smoking cessation period.
