1. Boys should respect girls' wishes and feelings and don't force her to video chat. If girls don't want to, they can try text chat, voice call or phone call to keep in touch.

2. Boys can try to communicate with girls and find out why she doesn't want to video chat. If it is because they are not confident about their appearance, boys can encourage her and tell her that they care more about her inner beauty than her outer beauty.

3. Boys can give some concrete examples, such as doing something together in video chat, such as watching movies or playing games together, to make girls feel more natural and comfortable.

4. Girls can also try their own methods to enhance their self-confidence, such as learning how to make up or match clothes, or exploring themselves and trying new things to make themselves feel more confident and attractive.

Most importantly, the two sides should maintain frank communication, mutual understanding and support. In the process of solving problems, the two sides can jointly explore new ways and means to meet each other's needs and preferences and establish a healthier, more stable and longer-lasting relationship.
