Wasn't Chao-Li like a genuine father figure to Lance? He tried to steer him in the right path in life and their tai chi martial arts moments were always pleasant to watch. Then there was Emma being treated like a daughter by Chao-Li. With all this considered should the China man's family been beefed up, maybe in season eight and have had less Ortegas around, to create room for them. A teenage grandson (Li-Ying's son) could have arrived on the doorstep, a trouble maker who grandfather Chao-Li would've had to keep in line. Slogging in the vineyards would have been part of this, a bit of the philosophy "Don't talk. Just Act. Don't say. Just show. Don't promise. Just prove."
