CHINA -- We keep learning more and more about what former Colts quarterback Peyton Manning has been up to since he retired from professional football.

Lately, Manning has been in China, helping the NFL promote its new China Arena Football League.

He took selfies with fans:

Cruised down the Great Wall of China in an alpine roller coaster, yelling at the person in front of him to speed up:

And hung out with former NBA player Yao Ming, one of the only people to make the 6-foot-5-inch athlete look short. Yao Ming is 7-foot-5-inches tall.
