The main building of the forum island is the main forum and sub forum. We use the "rich bamboo (foot) Yin Shi (real)" with beautiful implication to point out the topic. As the main building materials of the main sub forum, the "bamboo" and "stone" are not only because of the local prosperity, but also because the material technology is unique to China and leading in the world. This will be our achievement display and determination in the ecological field expression. At the same time, we use the homophony of "rich and substantial" to express our wish for "national peace and security".
