Legally speaking, it makes no difference, because none of them are official novelty retrieval reports. The difference is that your search may not be professional enough, because you only use the patent database in China, and the database queried by the search software of patent agencies is all over the world.
If you want to do project approval or evaluation, you should go to the novelty retrieval station of the patent office or government department, and they will issue a novelty retrieval report, which can be used for project approval and asset evaluation.
