Yang Ye
After Yang Ye's reluctant surrender, Emperor Taizong awarded his family an impressive mansion in the capital Kaifeng called "Heaven Wave House". Gratified, Yang Ye swore allegiance to the emperor and defeated the Liao Dynasty forces from Song's northern borders again and again. The jealous Pan Renmei, also the emperor's father-in-law, offered to the emperor to name his son Pan Bao the vanguard, but the other ministers were not convinced since Pan Bao had no experience. Pan Renmei then offered to start a martial arts tournament in Kaifeng's Tianqi Temple, but specified that the Yang family shall not participate. The emperor agreed. Yang Ye locked his sons at home, but on the last day the 7th son sneaked out the house, joined the tournament, and killed Pan Bao who had been using underhand means to defeat his opponents.
