Two Russian friends wanted to climb on one of the world’s tallest buildings.
Aware of the strict Chinese law, they prepared carefully and picked an appropriate date, the Chinese New Year day. At that time the security was less watchful, workers were on vacations, and cranes did not work. They got to the crane at around midnight. It took them almost two hours to get on the 120th floor by foot. Then, they spent almost 18 hours on the top of the building, sleeping and waiting for better weather. You can see the result in this video.
