If you you pay attention enough to one of the buildings during your Hong Kong day trips, you may spot one or two buildings with a bamboo scaffolding around it.
This is because in Hong Kong, bamboo scaffolding is used as the primary method to build/renovate buildings. When you see one during your private Hong Kong tours, you will be amazed how the scaffolder assembled each bamboo rod making sure everything is properly placed and safe that it can carry a legion of workers.
