Why is the beach in Laoting black?

Leting is pronounced "Laoting". Yu Qiuyu read on TV that the word "乐" (pronounced yao, the fourth tone) in "The Benevolent Man Leshan" is "le" (pronounced le, the fourth tone). He obviously didn't understand it, but when others pointed it out, he quibbled that it was a polyphonic character. , should be pronounced according to the pronunciation "familiar" to most people. According to this, "Le Ting" should be read as "Le Ting" or "Yue Ting". It is a pity that people in Laoting and the whole country do not buy Master Yu's account and continue to pronounce "Lao Ting". The signs on the highway here are also marked with "Lao Ting" in Chinese pinyin, just like "Liu'an" in Anhui Province is pronounced as "Lu'an" "Same. This is beside the point. It is said that Leting originally had two major highlights: one was the hometown of Li Dazhao, which made it a "red tourist area". Second, Laeting drums, shadow puppets, and Yangko, known as the "Three Flowers of Jidong Art Garden", were all born here, making it a major traditional cultural county. In 2003, Leting was awarded the "Hometown of Folk Art" by the Ministry of Culture, and its education, science and technology and other work also ranked among the top counties in the province. In recent years, Leting has a new bright spot - beach tourism. Every summer, people from surrounding Beijing, Tianjin and Tang Dynasty come here for vacation, making Laoting even more famous. A few days ago, I went to Leting to cool off. But after the vacation, I felt heavy. On the first day, I discovered that the beach at Repulse Bay was gray and there was foam and debris in the sea. Unlike old tourist areas such as Beidaihe, it has not received tourists for a long time. The beach and sea water should be white and clean. As night fell, there was a sudden loud crackling sound, and colorful fireworks rose over the hotel for a long time. I thought there was some special incident and didn't pay much attention. The next day at the beach, based on my experience at other seaside beaches, I had a sand-burying therapy. Unexpectedly, after shaking off the sand, the whole body was stained black, and it took a long time to wash it off. Observing the beach carefully, it turns out that the white sand has merged with a kind of black powder; the beach that has just been soaked by the waves has black lines; looking around, the vast beach is littered with the remains of new and old firecrackers and various garbage - if it is not the long-term firecrackers, Fireworks will never have such consequences. Walking around the hotel area by the beach, I found that fireworks and firecrackers were on sale everywhere, the ones as big as heavy artillery shells, and there were also "luck draws". I saw several hotel advertisements, and they all said things like "Fireworks Display" and "Bonfire Party". I have been here for a few days, and fireworks and firecrackers are set off every night, deafening, and my heart tightens again and again. There are so many tourists, playing in the water and sand, but no one pays attention to this phenomenon. Asked several vendors who put the flowers, the answer was "Beijing people"; asked why, the answer was "burning money"; asked if anyone was in charge, the answer was, "I don't know." I'm very frustrated. If the causes of pollution in the Yangtze River, Yellow River, Taihu Lake and Dianchi Lake are complex and "inevitable", and although people cannot accept this, they can barely "understand" it, then the pollution at Laoting Seaside is inexplicable. How did such an obvious act of stupidity begin? Although the people who set off the fireworks lacked civilization, who had the bad idea to "advocate" and "permit the setting off" to turn a perfectly good beach into such a miserable state? They don't have any brains at all, do they? The fireworks are fun for a while, the merchants make a little money, and they contribute a little to the local GDP, but I think no amount of money and effort will be spent to restore the clean water to the dirty beach water - the extremely fine sand on the huge beach and the falling fireworks How to separate powders when they are mixed together organically? Sieve through a sieve? joke! Use sea water to wash? What a joke! Let it weather naturally in a few hundred years. From now on, people who go to Laoting Beach for vacation will inevitably be accompanied by sand mixed with gunpowder powder and unclean sea water; perhaps, they will also become unconscious producers of continued pollution. Some people say that China is now "polluted everywhere" and "everyone creates pollution." Although this is an exaggeration, it is not unfounded. It is said that this beachfront was initially "leased" to a Hong Kong businessman at an incredibly low price, and the latter promised to invest huge sums of money in "development". However, after many years of "opening" without "issue", it was "transferred" to a mainland company at a price dozens of times higher than the original price. The company then "transferred" it to some people at a price dozens of times higher than the "transfer price" - —Today’s tourist hotels are built by the latter two types of people. The company set up a frame at the entrance, and tourists had to pay to get in. As for safety, environmental protection, sanitation, and service quality... does this company control it? Have the tourism department and the government intervened?
