Qin Shubao
Yang Lin was the one who came up with the idea of Yangzhou's martial arts test. However, after the plan was proved to be a failure, Yang Lin and one of his adopted son, Yin Yue (殷岳), was ambushed by Qin Shubao and Luo Cheng. Yin Yue was killed by Qin Shubao during the battle, and Yang Lin was hurt by Luo Cheng. It was a great time for Qin Shubao to revenge for his father, but Qin decided to forgive Yang Lin, for Qin was also Yang Lin's adopted son and Yang Lin taught him a lot about military and martial arts. Also, unlike many other local governors or generals at that time, Yang Lin never did harm on but often protect common people, and that was why Qin Shubao respected Yang Lin though Yang Lin killed Qin's father. At that point, the dejected Yang Lin said that he never regretted to ask Qin Shubao to be his adopted son although later he knew Qin Shubao's father was Qin Yi, because Qin Shubao was a real hero. He said that he always respected Qin Yi for the loyalty he showed, but he had to kill Qin Yi because they were enemies at that time. He also told Qin Shubao that Sui Dynasty might not be able to survive at this point, but the good future of the common people would be relied on heroes like Qin Shubao and Luo Cheng. After that, Yang Lin committed suicide by cutting the throat.
