Luoxing Tower and Majiao at the foot of Ma Jian Mountain face each other across the sea. The tides in this section of the river vary greatly, especially in the spring tide in August. "When you leave Haimen alone, it suddenly becomes dry and white. Wave three thousands of feet, stone horse is invisible. " Lin Shibi in the Ming Dynasty, "Crossing the Yangtze River to the East, Waves Return to the White Horse for Autumn Wind". Why does it snow so heavily in the mountains? Just like "Qiantang in mid-August", comparing the tidal observations of Luoxing Tower and Qiantang in Hangzhou, there are many wonders. However, there are times when the tide rises and falls under the Luoxing Tower. For example, Xie has a poem saying: "The dragon sleeps in the empty river, and the tide returns to the wild crossing. In the middle of the song, the night is far away, and the fishing fire is unknown. "
The situation of Luoxing Tower is dangerous: "The land is like Qutang to see the beautiful scenery, and the Yangtze River in the river to see the golden coke." 1559, Yin Feng, a subordinate of Qi Jiguang, defended his ponytail and beat the enemy. 1656, Zheng Chenggong went north to fight against the Qing Dynasty, built a fort in Luoxing Building and trained the navy. 1884, the tragic death of more than 800 naval officers and men was witnessed by history. Therefore, it is stated in Fujian Tongzhi that seven provinces (from Liaoning to Guangdong) are the best, surrounded by heavy mountains and locked at different levels.
