"That is to say that the PLA troops are compelled to enter the capital in order to restore the normal order in Beijing, maintain public security, and prevent important government organizations from being affected or stormed. I would like to explain this point clearly to all those who are present here. The PLA troops' arrival is definitely not aimed at dealing with the students. It is hoped that all trades and professions, people in various circles, and particularly people of the various democratic parties will support the PLA troops for their action to safeguard the capital and maintain public security. I hope that you will give them your full understanding and support. This is the point that I wanted to explain to you comrades here. I have nothing else to say. That is all."
