Actually, organ harvesting first started with the Uighurs in China because, more or less, they are supporters of Falun Gong either secretly in government or in civil society. So if anything happens, immediately people make it public. For that reason, they have more access to information, and access to information is not that strict for ordinary Chinese citizens. For Uighurs and Tibetans, it is absolutely a no-right zone.
For that reason, for example, now hundreds of thousands of Uighurs have been transported to mainland China, totally separated from their families, totally separated from their cultural roots. What is the consequence waiting for them? There is organ harvesting for hundreds of thousands.
The Chinese government doesn't hesitate to turn Uighurs' bodies into money. Instead of feeding them three times or twice, their organs are used and the bodies are burned in a crematorium. That is the practice of the Chinese government. Organ harvesting is more severely under-reported for Uighurs than for any other people in China.
