The Nanyue National Sluice Site is located on the B1 floor of Guangming Square, 63 Xihu Road, Yuexiu District, Guangzhou City. As soon as you enter the first floor of Guangming Square, follow the guide and take the escalator down to the negative floor, you will see the South Vietnamese National Sluice Site. The sluice is one of the earliest, largest and best preserved wooden structure sluice sites in China. The glass protective cover of the existing cultural relics sites is protected in situ and is open to the public for free visits. The Nanyue National Sluice Site was declared as a municipal cultural relic protection unit by the Guangzhou Municipal Government in 2002. In May 2006, it was declared a state-level cultural relic protection unit. However, there are more staff here than tourists. Moreover, the lighting of the exhibition hall here is rather dim, and it is difficult to see the site of the sluice through the glass protective cover.
