Richard arranged for Ren He to join the class of freshman undergraduates from the '06 class, which amounted to setting him free to roam: "You enjoy the unrestrained campus life, so there you go, roam free."
Frankly speaking, it was because Richard himself did not know what to teach Ren He anymore.
The painting "Stubbornness" is currently on display in Richard's office, and Ren He planned to take it back to his Courtyard House in China when he returned home.
The painting is very valuable. Previously, due to Richard's influence, it had been evaluated with an initial price tag of 10 million US Dollars, and at the time, many people deemed this valuation inflated. Various businessmen, having low estimations of this previously unknown piece, didn't think it was worth 10 million US Dollars.
