Hi Cha Cheolun. You've got vaccinated and taken COVID tests before your arrival in China, these information will not be shown in your Jiangsu Health Code (su kang ma). As for results of your tests and vaccination taken in China, the information will be automatically uploaded to the system and shown in you su kang ma.
