Vitaly Raskalov  :-
"Aware of the strict Chinese law, we 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. We got to the crane at around midnight. It took us almost two hours to get on the 120th floor by foot. And also, we spend almost 18 hours on top of the building, sleeping and waiting for better weather. The result you can see in our new video."
