Why did Shan Xiongxin call Qin Qiong's name when he died in "Sui and Tang Interpretation"?

The reason Shan Xiongxin did this was to pave the way for Qin Qiong, and he did not want Qin Qiong to be suspected by Li Shimin because of himself.

Shan Xiongxin and Qin Qiong were both from Wagang, so they can be said to be brothers. They also defected to Wang Shichong together, but Qin Qiong and Cheng Yaojin chose to leave Wang Shichong and join Li Tang very early. After all, Qin Qiong had not taken refuge with Li Shimin for a long time at that time, and Shan Xiongxin did not want Qin Qiong to be implicated because of him.

The reason why Shan Xiongxin was killed:

In fact, the key to why Li Shimin insisted on killing Shan Xiongxin lay in Shan Xiongxin’s character. At that time, ability was important, but character was even more critical. A wavering person, no matter how brave he is, may not be reused if he is not loyal enough.

You must know that many generals who surrendered to the Tang Dynasty rebelled one after another at that time. This was a blow to the Tang Dynasty and Li Shimin. Before Shan Xiongxin surrendered to the Tang Dynasty, Li Mi rebelled. Therefore, in Li Shimin's view, such a disloyal person is just a loser and cannot be trusted.
