Nimen hao, Thingiversians!
You can try to print the entire map at once if you're an expert in this sort of thing, but I've found printing provinces individually or in groups to be far more productive. I've broken up the provinces into six groups, with no organization short of shared borders:
group_0: hebei, shandong, jiangsu, henan, shanxi
group_1: guangdong, fujian, taiwan, zhejiang, anhui, hubei
group_2: nei menggu, heilongjiang, jilin, liaoning
group_3: gansu, ningxia, shaanxi, chongqing
group_4: sichuan, yunnan, guangxi, guizhou, hunan, hainan
group_5: xinjiang, xizang, qinghai
The suffix _disputed indicates a piece or group that reflects the territorial conflict between India and the PRC in southern Xizang.
Although they are legitimate political divisions of the PRC, Hong Kong, Aomen, Beijing, Shanghai, and Tianjin are not featured in this map because of printing scale limitations.
PDF files in English, Pinyin, and Simplified Chinese are included in the archive.
Printing tip: Print groups in PLA, and press the pieces together while they're still warm. It'll help if there's any distortion.
