The ancient silk road, forests, desert, sand dunes and a treasure trove of flora and fauna: every year, Xinjiang Uygur Autonomous Region, in the centre of Asia attracts huge numbers of tourists from all over the world. In the first half of the year, the region welcomed 1 million visitors. But on July fifth all that changed.

It was almost a year ago when the curtains came down on the Beijing Games. The stadiums are empty and there isn't a sports star in sight. But thousands of people from across China still flock here every day for their very own Olympic experience.

The Bird's Nest gets as many as 20,000 visitors a day. They pay the equivalent of about seven dollars to enter the empty stadium and buy souvenirs.

Outside, thousands of visitors from every corner of China snap photos and look on at what has become something of a national treasure.

Considered an alternative medical system in much of the Western world, in China, Traditional Chinese Medicine, or TCM, is a valuable cultural treasure for over one billion people. While it attracts increasing attention in western countries, in China fierce debate over its legal existence has been raging on for over one hundred years. With thousands of years of history and a variety of almost magical treatment methods such as acupuncture, herbal medicine, food therapy, cupping and Tuina massage, TCM has never been without its side in western eyes. That's not to say however that doubts surrounding its efficacy and safety, as well as longstanding confusion over its development in China don't exist. Such uncertainty has resulted in a new wave of debate over whether to preserve or abolish this living symbol of Chinese culture.

Nick, I mean Agent Nick, must find a 6000-year-old person (that's right, a 6000-year-old person). If you want to know if he succeeds or not, you have to watch the episode.

Agent Nick sets a fish free, and acts out scenes from classic Chinese novel "Dream of the Red Chamber."

Agent Nick passes out in the middle of nowhere and gets dragged along the road for like, a good 3km. He also completes his final mission (for the time being, at least), which makes him go crazy and run around in public, screaming like a maniac.
