Mangrove is a unique evergreen shrub and small tree community in tropical and subtropical bays and mudflats of estuaries. It grows in the shoal of the land-ocean junction zone and is a special ecosystem of land-to-ocean transition. The prominent feature is that the root system is developed and can grow in the sea water. In fact, mangrove ecological park has been built in many coastal areas of Shenzhen, so there is no need to go to which mangrove. My sister said that mangrove is the place where they jog after work and walk after dinner, blowing the sea breeze, and greening a very good park. There is no beach on Shenzhen's coastline. It's full of reefs. When taking photos, I accidentally looked back and found a big rotten dead fish lying in the crack in the stone beside my feet.
