Zhuhai announces Macao Health Code. Can I declare again if I succeed?

Yes There is no limit to the number of times you can declare your health code. As long as you provide your ID card, you can enjoy free nucleic acid testing in China. If the entry-exit health declaration has been made, you can choose to click "Submit" directly; If the information changes, you can choose "Re-declare". After completing the health declaration according to the prompts, I will get my Guangdong-Kangma customs clearance certificate.
