During his detainment, the Bureau of Ethnic and Religious Affairs leaders and the State Security department interrogated Mr. Chen. They tried to get him to stop preaching the gospel on the streets.

Mr. Chen was released on the 8th of July. Throughout his time detained, CCP security officers communicated with him almost continuously. They told MR. Chen that they knew exactly where he had preached the gospel over the last two decades.

According to China Aid, CCP authorities knew all of the trips Mr. Chen had made in that timeline to different places throughout China, as well as the individuals who had traveled with him. The officers even had documented when Mr. Chen had traveled with four other Christians through numerous countries on their way to Tibet, where they preached the gospel.
