Update: After reading further information from AsiaNews on the funerals of Bishop Paul Xie Tingzhe, bishop of Urumqi (Xinjiang), and that of Bishop Sylvester Li Jiantang, who died only 13 hours apart, it was explained that Bishop Li had been in labor camps, but subsequently left the underground Church and joined the government-controlled Patriotic Association. The two funerals are a striking contrast as you can read in the report here from AsiaNews..
