This was an ancient custom: ringing the bell when opening the city gates at dawn, beating the drum when closing them at dusk, and hence it was called the morning bell and the evening drum.
As the city gate was about to close, Peng Fu suddenly shouted, "Hold on!"
The city guards were startled, but then they saw Peng Fu. Peng Fu directly tossed them a small ingot of two taels, asking, "Have you seen Zheng Chuan?"
The city guard caught the ingot and was immediately overjoyed. Today really was a good day.
Just a moment ago, Zheng Chuan had left the city and given them a small ingot, and now they had received another.
With this thought, the city guard said, "I have seen him, he just left the city not long ago."
Upon hearing this, Peng Fu continued, "Which direction did he go?"
The guard hesitated slightly. Zheng Chuan had given him money and told him not to disclose the direction to anyone.
