"If Du Xiangbao killed Du Daguai, it must have been because of some conflict between them. I think we should investigate the origin of that conflict," Su Qing said after a moment's thought. 'She knew full well that Du Xiangbao and his crew were tomb robbers, but she couldn't say so outright. She could only try to guide them gently.'
"Right, we're considering that angle too, but we haven't turned up any results yet," Zou Ming said with a nod.
"What about Du Xiangbao's occupation? Have you found out what he does?" Su Qing asked.
"He's an unemployed drifter," Zou Ming said. "After he left your Lihua Village, his movements were erratic, but it's certain he never had a steady job. Then, a little over a year ago, he suddenly showed up in Beijing and found Du Daguai. After that, he was a frequent visitor at Du Daguai's home. This information came from Du Daguai's neighbors."
"Besides Du Xiangbao, was no one else looking for Du Daguai?"
"No."
