My office view is next to an apartment building, one day a bunch of Scaffolders arrived, erected an 30+ storey high bamboo scaffolding structure in less than a few days. I think they were painting the exterior facade or something. After they were done, it literally took them 2 days to dismantle everything. Really impressive to watch their skill and teamwork. In the wise words of Jackie Chan: Don't worry, Chinese Bamboo Very Strong
