Does Guilin health certificate need to be processed in the morning?

Need. Generally, if you want to get a health certificate, you are advised to go in the morning. In the meantime, you need to test your liver function. If liver function is needed, fasting is forbidden. If you go in the afternoon, fasting for too long will easily lead to hypoglycemia and the test results will be inaccurate, so you should apply for a health certificate in the morning.
