If adolescent girls are found to draw yellow paintings, they should first remain calm and rational to avoid excessive panic or overreaction. It is very important to know the situation of children and give them proper attention and support.

Here are some possible suggestions (in no particular order):

1. Respect children's privacy: Although children are found to be drawing small yellow paintings, don't rummage through their belongings and don't question them at will. You can try to talk to your child and let her know that you care about her and respect her privacy.

2. Give support and attention: Let your child know that you support her and pay attention to her growth and development. You can try to ask your child if he has any troubles or pressures recently, help him solve some problems or provide some suggestions.

3. Give children proper attention and love: If children are interested in sexual content, it may be because the demand for love and attention is not met. You can try to care more about children's life and study and give them more love and care.

4. Guide children to treat sex correctly: Although children's interest points to Xiao Huang's paintings, they can also try to guide children to treat sex correctly. You can try to talk to children about the positive and negative aspects of sex and help them form correct values and outlook on life.

5. Seek professional help: If you can't handle this problem or you think your child may have other problems, you can consider seeking professional help. You can try to communicate with your child's teacher or other professionals and ask for help and support.
