I don't understand Temu.

Here's the conclusion from the official 2022 UN report: https://www.ohchr.org/en/documents/country-reports/ohchr-assessment-human-rights-concerns-xinjiang-uyghur-autonomous-region

"Overall assessment and recommendations

143. Serious human rights violations have been committed in XUAR in the context of the Government’s application of counter-terrorism and counter-“extremism” strategies. The implementation of these strategies, and associated policies in XUAR has led to interlocking patterns of severe and undue restrictions on a wide range of human rights. These patterns of restrictions are characterized by a discriminatory component, as the underlying acts often directly or indirectly affect Uyghur and other predominantly Muslim communities.
144. These human rights violations, as documented in this assessment, flow from a domestic “anti-terrorism law system” that is deeply problematic from the perspective of international human rights norms and standards. It contains vague, broad and open-ended concepts that leave wide discretion to officials to interpret and apply broad investigative, preventive and coercive powers, in a context of limited safeguards and scant independent oversight. This framework, which is vulnerable to discriminatory application, has in practice led to the large-scale arbitrary deprivation of liberty of members of Uyghur and other predominantly Muslim communities in XUAR in so-called VETC and other facilities, at least between 2017 and 2019. Even if the VETC system has since been reduced in scope or wound up, as the Government has claimed, the laws and policies that underpin it remain in place. There appears to be a parallel trend of an increased number and length of imprisonments occurring through criminal justice processes, suggesting that the focus of deprivation of liberty has shifted towards imprisonment, on purported grounds of counter-terrorism and counter-“extremism”.
145. The treatment of persons held in the system of so-called VETC facilities is of equal concern. Allegations of patterns of torture or ill-treatment, including forced medical treatment and adverse conditions of detention, are credible, as are allegations of individual incidents of sexual and gender-based violence. While the available information at this stage does not allow OHCHR to draw firm conclusions regarding the exact extent of such abuses, it is clear that the highly securitised and discriminatory nature of the VETC facilities, coupled with limited access to effective remedies or oversight by the authorities, provide fertile ground for such violations to take place on a broad scale."

However, it is noteworthy that if one were in China and were to criticize the government or comment on the uyghar issue, you will find yourself being sentenced to prison. Possibly up to a life sentence.
