《资治通鉴·汉纪·汉纪二十三》
成帝后悔弃置王谭，使他没有担任辅政大臣就去世了。于是再次任用成都侯王商，让他以特进身份主管城门兵，设置幕府，使他与将军同样有举荐官吏的权力。
上悔废谭使不辅政而薨也，乃复成都侯商以特进领城门兵，置幕府，得举吏如将军。
Emperor Cheng regretted discarding Wang Tan and making him pass away before he could serve as the minister of state. Therefore, he once again employed Cheng Duhou Wang Shang, who would supervise the city gate soldiers as a special envoy and establish a military strategist manor, giving him the power to recommend officials, just like the generals.
