The main thing is to look at yourself and go out more. Now that society is so open, it should be easy to meet the opposite sex. If your circle is small, expand it. You can consider cultivating some hobbies, such as joining a reading club, a small running group, a mountain climbing and cycling group, a computer game group (some games are suitable for both men and women), or even hanging out on Zhihu all year round. There should be a platform where you can show yourself and let others get in touch with you. With this platform, you will not be embarrassed to communicate with others. Now that the Internet is so developed, you can get to know many people even if you are too lazy to go out.
