On September 1999, we have collaborated with the famous architect I.M.Pei to accomplish the rockery project for the interior of the Bank of China. The rockery construction took Lin Rock from Yun Nan province at 3000 kilometre away. The rockery scenery is surrounded by bamboo from the southern region of the Yangtze River as a background. Overall it adds the Austral atmosphere to the northern city such as Beijing.
