Hello, if the system can't get abnormal data during the annual review of Guangdong Business Connect, you can try the following methods:

1. Check whether the network connection is normal. If the network is unstable, data collection may fail.

2. Please refresh the page or log in again. Sometimes data loading failure is a system failure, and reloading or logging in may solve the problem.

3. Contact the customer service or industrial and commercial department of Yueshangtong. If the above methods can't solve the problem, you can consult Yueshangtong's customer service or industrial and commercial department, and they can provide technical support or solutions.

4. Try to use other methods for annual review. If the above methods can't solve the problem, I suggest you try to use other methods for annual review, such as on-site handling.

I hope my answer can help you.
