What does Mr. Qin mean?

When Jia Jialou, a 46-year-old friend of Sui and Tang Dynasties, became sworn, he ranked second and was called Master Qin.

Qin Qiong (? —638), the word Uncle Bao, was born in Licheng (now Jinan City, Shandong Province) and was a famous soldier in the late Sui and early Tang Dynasties. He was a general in the Sui Dynasty. He has studied under Huer, Zhang Xutuo and Pei, and is famous for his bravery. Later, Pei went to Shi Mi, the leader of Wagang Army. After the defeat of the crock, he defected to the king. Seeing the treachery, the king defected with Cheng and others. After entering the Tang Dynasty, he fought against Li Shimin. He is a brave general who can take the head of an enemy general in an army of ten thousand horses, but he is hurt all over. After the Tang Dynasty, he died after a long illness in the twelfth year of Zhenguan. Before his death, he was General Zuo Wuwei and Yong Guogong. After his death, he was posthumously awarded as Xuzhou Governor and Hu Guogong, which was called "Zhuang". Zhenguan was listed as the twenty-four outstanding figures of Lingyange in the seventeenth year.

I hope it helps you.
