From the intersection of Zhenjiang Grand Canal and the Yangtze River to Hanshan Temple next to Suzhou Ancient Canal, Jiangnan with dense water network makes people feel very close, and there are so many stories that people have no clue. Following it, we can pick many beautiful legends and stories as easily as picking willow leaves on the bank of the canal. The legendary story of the battle between Liang Hongyu and Jinshan has always been fresh in people's memory.

Liang Hongyu, a Huai 'an woman, was forced by life and served in Jingkou Military Camp. One afternoon at 5 o'clock, she went to the office on business. Just as she entered the door, she suddenly saw a big Hei Hu sleeping under the pillar in front of the porch, snoring like thunder. On closer inspection, she found that it was a guard. The sleeping guard is Han Shizhong. When Liang Hongyu returned home, he told his mother about seeing Han Shizhong and decided that Han was by no means an idle person. So the mother and daughter soon invited Han to their home to entertain them warmly. In the long run, congenial Liang Hongyu and Han Shizhong got married.

Liang Hongyu has a good eye. Later, with the personal help of Liang Hongyu, Han Shizhong repeatedly made meritorious military service, became a famous star in the Southern Song Dynasty, and was promoted to be king. Liang Hongyu was also named Lady Anguo. "Because of the Grand Canal, the city is more prosperous, and many stories in the city enrich the history of the canal." An old gentleman of Jiangsu Provincial Political Consultative Conference said this. My understanding of the Grand Canal is "alive", not only flowing, but also constantly changing. On the other hand, the legend lingering in this city makes the Grand Canal more vivid.

The Grand Canal is lively, and its practical function makes it indispensable. Jiangnan Canal basically maintains the shipping function, so it is necessary to combine its application and protection with practical use at present. There is such a set of data: the Beijing-Hangzhou Grand Canal flows through eight cities in Jiangsu Province from north to south, including Xuzhou, Huai 'an, Yangzhou, Wuxi and Suzhou. The total GDP of these eight cities has accounted for more than two-thirds of the province for several consecutive years. In Suzhou, where the economy is developing rapidly, there are more than 1 300 transport enterprises whose annual traffic volume on both sides of the canal exceeds110,000 tons. The shipping value of the canal is prominent and has become an important force to promote economic development.

"Utilization is a way, but utilization must be planned." This is what Mr. Luo, an expert on ancient architecture, has always emphasized. Wuxi's practices in canal protection are worth learning. In the afternoon, we finally found the canal family by the Wuxi Canal. On both sides of the river, the old houses with a history of more than 100 years are simple, but primitive and simple, and they are still the shelter of ordinary people. With the use of tap water, there is no need to wash the toilets in the canals, and everyone can take on the responsibility of protecting the canals more consciously. By the end of the year, a flood control river bypassing the urban area will be completed. By then, the ancient canal will no longer take ships with large tonnage and heavy pollution, and there is no need to worry about water overflowing during the rainy season, which will affect the old houses on the shore.
