Old Master Zhang went upstairs after hearing what Zhang Zhentian had said. The night was destined to be another sleepless one, with Old Master Zhang unable to sleep because of what Zhang Zhentian had said, and Zhang Zhentian himself restless over concern whether his father would change his attitude.
After Old Master Zhang returned to his bedroom and lay in bed, he thought about what Zhang Zhentian had said to him. He felt it made sense; he was well aware that Zhang Zhentian had appealed to his weakness to ask for leniency for Xia Jing. Zhang Zhentian understood his father valued pride greatly, hence he had exploited Old Master Zhang's "face theory" to plead with him.
