The first successful hand reattachment surgery in China had been accomplished back when China's medical conditions and environment were still really poor. That was something amazing. One of the primary surgeons for that surgery was connected to Qiu Fazu, the father of modern Chinese surgery.
Back then, China had yet to import even one slightly advanced medical microscope. Despite this, the medical geniuses of that generation had managed to succeed at hand reattachment surgery. But after that, after a certain period of time, Chinese society became such that money was considered more important than anything. Limb replantation surgery swiftly went down a downhill slope in Chinese medical development, despite other Chinese medical fields rapidly advancing to catch up with the rest of the world. All of this was due to the lack of benefits associated with limb replantation surgery for Chinese public hospitals.
