Lu Lianghong is surrounded by mountains, and the riverbed is not easy to swing. There is a line in Wen Tianxiang's poem "A Journey to Pengcheng", which is a true description of this landform. Lv Lianghong is more dangerous than Xuzhou flood, which is divided into two major floods (Lvliang to Xiahong Village, Yizhuang Town, Tongshan County), extending for more than seven miles. Yuan, Zhao and Meng's "Inscription of Lvliang Hongguan (Feather) Wei (Chigong) Temple" describes the difficulty of crossing the Lu by boat: "... The boat arrived here, full of poles, and the people carrying the cable sweated into the size. The hard part is that he climbed to the sky, and people on board often called for leave to help the gods. " To the southeast of Lu Lianghong is Tashan (now called Guan Feng). In the 24th year of Jiajing in Ming Dynasty (1545), there is still a tablet of "Shu Chixing Lvliang Hongji" on the site of Confucius Temple in Tashan. Xu Jie, assistant minister of the official department of the Hanlin Academy, assistant minister of the punishment department, and He Changhan were written by famous calligraphers. It has high artistic value and claims to be. This monument provides us with specific historical data on the governance of Lu, and also describes the sinister situation. Jiajing's Lvliang Hongzhi describes it in more detail, saying that it is difficult for a boat to go upstream, almost in terms of size. It also describes the slide of large stones in the flood. The so-called stone slippers, that is, the boulder in the water is hit by the rapids and becomes smooth. These stone slippers are famous for their fierceness, such as Lujia slippers, threshold stones, Huangshi slippers, free frog stones, hag stones, drinking wheel stones and so on. Ships passing through these stone landslides must rely on the help of trackers. In the Ming Dynasty, Jue Yuan went to Beijing as an official and experienced two floods. He recalled his experience on the Lvliang Temple Monument in Xuzhou: "The capital was in Huan, and after today's Lvliang, the spring water was strong and the rocks were everywhere, so it was no longer divided. There are many drums in the boat, and the drums are strong and childish, and they are at loggerheads with the foot of the cliff. Those who also raise water for training specialize in stabbing water. When it dries up, the rocks are exposed, the foam hangs on the water surface, and it turns back into the abyss, and the beam is a flying spring. For a moment, I didn't want to watch it. Therefore, all ships must pray to God. "
