To verify a technical company in Beizhen, a process similar to that in other cities would be followed. Here’s a step-by-step guide:

1. **Check Official Channels**: Start by visiting the official website of the local government (usually ``). Look for information about authorized technical companies or relevant business registration pages.

2. **Search Business Registry**: If the official website doesn’t provide sufficient information, search Beizhen’s business registry system, which often has a dedicated portal for companies.

3. **Verify Company Information**: Once you find the company, verify their technical capabilities by checking their licenses, certifications, and past projects. You may also contact them directly to ask for verification or references.

Remember that the process might vary slightly based on Beizhen’s specific regulations and systems.
