Choose an original photo as the avatar and put it on the first one.
Exploration is the real avatar mechanism, so if the first photo is a non-avatar photo and the face is not clear, it will be easily blocked by the system and cannot be used again.
Put multiple photos in your profile.
In exploration, photos are the most intuitive way to get to know you. So, put more photos of your life or take selfies to show your dress taste, hobbies, travel experiences, etc. People who see you can know you better through different photos.
Create an interesting and unique profile.
Personal signature, constellation, occupation, label, etc. Can be a good chat topic. Therefore, if you want to get more likes, you should make yourself an interesting and unique person and stimulate others' interest in you.
Turn on the "super exposure" privilege.
If you want to get more likes, you need more exposure. If conditions permit, people can open the relevant privileges of exploration to increase their exposure and let more people see you before they like you.
