Over the years, I have observed that the frames for building a high-rise structure are very different in different parts of the world. In the west the frames are made using metal materials, which are usually heavy and dangerous, because they conduct electricity and heat. On the other hand, in China and Hong Kong, the frames are made of bamboo. The pictures below were taken in 1975. You can see that they are as good as metal-made frames, while they are easy to construct and very functional.
There are many other useful gadgets made of bamboo, such as back scratchers, ear cleaners, even musical instrument like flutes, and brooms. Why do you rarely see bamboo used in the west? Why is there a culture difference in using this kind of material!
