If the hotel's network score is poor, you can find your own staff to make a reservation and evaluate it.

You can't. In order to ensure the objectivity and fairness of the evaluation, the hotel network rating should come from the real customer evaluation, rather than being artificially operated by hotel employees or other agents. Hotels should take active measures to improve service quality and customer satisfaction. They should also listen carefully to consumers' complaints and suggestions, and solve these problems in time to improve service quality and brand image.
