Techeng Island is only 2.8 nautical miles from xiashan district, Zhanjiang City, and the voyage is about 8 minutes. It echoes the modern Zhanjiang port and the military port. Surrounded by mangroves, Mimizaza, Songcui Tuantuan and Bird Team have been in the sea for thousands of years. When entering the forest at low tide, I saw mangroves with large washbasins with thick roots, upside-down trunks, blooming branches and leaves, and beaded fruits, giving people a kind of spirit and strength.
