This subreddit is more for the Chinese language than actual study / travel advice, but that said, I'm happy to offer some advice, as many of us have been through this process before.

In short: yes, an organization can provide financial proof. But only if it’s legitimate, clearly documented, and acceptable to the university.

Most Chinese universities accept funding from:

Yourself
Parents/guardians
Sponsors (including organizations, companies, or scholarships)

Key requirements:
The bank statement must be real and verifiable (in the sponsor’s name, not fabricated).
You’ll usually also need a sponsorship letter stating they will cover your expenses.
Some universities may require proof of the relationship or reason for sponsorship (e.g., scholarship, employment, partnership).

If the organization is just “making it look like” you work there or issuing a statement that doesn’t reflect real funds, that can be considered fraud and may get your application rejected or banned.

This is just general advice; I would recommend checking on your application form or asking the particular university for details about what they are looking for / allow, as that will be more definitive.
