The same. This set of national health code system developed by Alipay is composed of green code, yellow code and red code, realizing one code nationwide. Different colors have different functions: the green code corresponds to "passing by code", the yellow code corresponds to "real-time isolation within 7 days, and the healthy punch card will normally turn green for no more than 7 days", and the red code corresponds to "isolation 14 days, and the healthy punch card will normally turn green for 14 days". So my Lianyungang and Alipay health codes are the same.
