Here's a video that has Chen Xiaowang being 'rooted' against a couple of different people - the video is corny, and it's Chinese, but it probably the closest video you'll find to the tenryu/osensei deal.

At 3:28 you can see him getting pushed on by a guy that is around 400 pounds.

At the end of the video is him trying to stay in the a circle getting pushed on by a strongman. Here's a the part where the strongman is pushing a semit-truck with a trailer:

Here's the 3 1 minute rounds start at the end where the strongman tries to push Chen Xiaowang out of the circle.

I don't speak Chinese but I would like to know what the strongman is saying at the end after pushing on CXW.
