The most bitter chapter of South Emperor Deun Chi Hing's life is when his concubine Ying Goo had an affair with Chow Bak Tung while the emperor trained the 1 Yeung Finger Technique in seclusion with Central Divinity Wong Chung Yeung. The affair, the subsequent murder by Kau Cheen Yan of Chow and Ying's bastard son, and the emperor's hesitation to heal the child (which might have ended up costing the child his life) tormented Deun for years, even after he became the Buddhist monk 1 Deng.
Many decades later, thanks to Yeung Gor and Gwok Seung's intervention, 1 Deng, Chow Bak Tung, and Ying Goo were able to make peace with the mistakes of the past and with each other. That said, why did 1 Deng choose to settle down near Chow Bak Tung and Ying Goo? Just because they buried the hatchet at long last doesn't mean they necessarily wanted to face each other day in, day out as neighbors. As a former emperor of Dali, wouldn't 1 Deng have preferred to spend his final years back in his homeland?
