This doesn't seem like something you can fix on your end, but I wanted to bring to your/others awareness that I noticed the values of confirmed cases reported in Changchun and Jilin City were flipped on 3/15, which has thrown off cumulative cases since.

Per NHC on 3/15 (http://www.nhc.gov.cn/xcs/yqtb/202203/8d8d2035b3884fcfb734e0ab07bede79.shtml):

Changchun: +460
Jilin City: +2601

Per DXY scrape:

Also, just a thank you for your continued support of this service. I started using these data early in 2020, and they've continued to be valuable some two years later. I've used them to provide situational awareness to US Government and colleagues internationally. I've found no better publicly available source of ADM2-level data to date.

Cheers!
