According to multiple sources, although any Tibet-related content the government deemed 'sensitive' were targeted by Chinese authorities for censorship on WeChat.

There have also been many cases of Tibetans being faced lengthy jail sentences for sharing chat messages, songs, and photos on WeChat with content related to His Holinessthe Dalai Lama and Tibet's religious, cultural, and linguistic heritage that Beijing authorities alleged carried "anti-China" sentiments.

The Chinese app performs censorship on the server-side. There were reports that when a message passes through a remote server that contains rules for implementing censorship. If the message includes a keyword that has been targeted for blocking, the message will not be sent.

Since that time, over 1.2 million out of 6 Tibetans have been killed, over 6000 monasteries have been destroyed— the acts of murder, rape and arbitrary imprisonment, torture and cruel, inhuman and degrading treatment were inflicted on the Tibetans inside Tibet. But, authorities in China still claim that "China 'peacefully liberated' Tibet, and that the Tibetans are living in a "Maoist socialist paradise."
