Introduction to the "Sun Yat-sen Historic Trail" stele: The upper part of the "Sun Yat-sen Historic Trail" stele shows the Blue Sky White Sun Flag and Sun Yat-sen's head, and the lower part shows the Chinese and English introduction and location map of the "Xiangshan Chamber of Commerce". Zhongshan, known as Xiangshan in ancient times, was a must-stop for the Maritime Silk Road that began in Guangzhou in ancient times. After the Portuguese occupied Macau, due to its special geographical location, Xiangshan gradually became the intersection of Chinese and foreign trade and Chinese and Western culture. As a result, commerce developed rapidly and became a regional business center. Thus, the Federation of Industry and Commerce was born.
