If you want to find someone in the same city who doesn't have a name and phone number, you can try the following methods:

1. Social media search: You can search the relevant information of the target area through social media platforms (such as Weibo, WeChat, QQ space, etc.). ), such as urban agglomerations, urban dating websites, etc. Post for help, post for your search, or search for relevant information directly through keyword search.

2. Local public security organs: You can ask the local public security organs for help and provide relevant information. They may give some help or provide relevant clues.

3. Non-governmental organizations: Find relevant organizations and seek help. Some non-governmental organizations and volunteer groups will provide services such as finding missing persons and helping to solve family disputes.

Please note that when conducting such searches, you need to abide by relevant laws and regulations and respect the privacy and rights of others.
