In fact, the Tang Army's special forces didn't know where General Feng Kezhi's command post was located; they raided one building after another, capturing Dahua military officers within for careful interrogation.
"You'd better start talking! Where is Feng Kezhi?" looming over a Dahua military officer who was kneeling on the ground with his hands over his head, a Tang Army special forces soldier questioned fiercely with an assault rifle in hand.
The officer was clearly terrified, as he was a civilian officer in the military, who had never been on the battlefield and didn't dare gamble with his own life.
So he immediately confessed, answering the Tang Army's question, "Across the street, in a courtyard over there, there's a basement..."
As a civilian officer, he had previously attended meetings at General Feng Kezhi's command post and even met General Feng Kezhi.
