The Great Wall in this area was about 5 kilometers long and there were 21 piers. Panjiakou Reservoir was built here, and the water level exceeded the height of the Great Wall, and xifengkou and Panjiakou Castle were submerged in the water.

3. What are the precautions for diving in summer
1. When diving, remember to proceed step by step, from easy to difficult, and don't rush for success. Diving is a systematic project. From the amateur who experiences diving for the first time to becoming a diving instructor with the highest level, the course content of each level is progressive step by step. After learning the corresponding level of courses, diving activities can be carried out in the waters corresponding to that level. Therefore, for your own safety, please don't rashly challenge high-level waters out of curiosity or other factors before receiving relevant training.
2. When diving, pay close attention to the diving depth to avoid discomfort caused by diving too deep.
3. Don't reach out and touch beautiful corals, tropical fish and other creatures to avoid accidents.
4. Stay close to the instructor when diving, and be sure to follow the instructor's instructions and follow the principle of two people walking together. Two-person peer system is one of the important principles of diving. That is, two people must stay together from entering the water to landing (going in and out together). Those with better skills (such as coaches) should not let their companions go ashore alone. Those who swim ahead (often those with good skills) must always look back at their peers and slow down with their physical skills. Those who swim in the rear (such as beginners) should stay behind their peers. Always keep in touch with the coach's gestures.
5. Choose a regular diving enterprise to experience diving activities. Regular diving enterprises should not only have the approved right to use the sea area, but also have all kinds of business qualifications, and strictly abide by the operating norms of experiential diving, which can ensure the diving safety of tourists and the price is moderate. Don't choose an informal diving enterprise that lacks safety protection measures and safety training for cheap.
6. Please check the equipment carefully before diving. Before each dive, check whether the equipment fits and functions normally, and learn how to use breathing tubes and regulators, how to rest on the water surface, and how to deal with emergencies.
7. When scuba diving, be sure to wear buoyancy control device and pressure gauge, and recognize the position of standby air source and low-pressure control inflation system. In addition to self-examination, peers should check each other again to make sure nothing is wrong. Be sure to test the equipment completely in the shallow pool before diving.
8. Carry the equipment on your back and walk into the sea with your diving partner (beginners should not learn to flip back and jump). When the water reaches your waist, put on your diving mask first and help your partner put on his flippers. After all this, put the regulator in your mouth and start breathing from the second decompression part. Turn back, wipe your feet and continue to retreat to the sea to prevent tripping due to the inconvenience of flippers.
9. After reaching the predetermined diving place, follow the instructor's natural slope along the bottom of the sea and gradually dive into the sea. For the first time, the dive depth should not exceed six meters. On the way to dive, you should always observe the water pressure gauge and grasp your depth.
Fourth, summer diving equipment
You need diving equipment to dive. Simply put, diving equipment can be divided into two categories: light equipment and heavy equipment. Light equipment refers to diving goggles, breathing tubes and flippers-the three treasures of diving. You only need these three pieces of equipment when snorkeling. Scuba diving also needs heavy equipment such as breathing regulator, buoyancy regulator, diving instrument, gas cylinder and other auxiliary equipment.
1. Three treasures of diving
Diving goggles, breathing tubes and flippers are collectively called the "three treasures" of simple diving, and Snorkeling is also translated as snorkeling.
1) mask
a window to enjoy the underwater world. Wear it on your face and cover your eyes and nose. Its main function is to enable divers to clearly observe the scenery in the water. Prevent nose from choking and balance ear pressure.
The goggles are composed of lenses, frames, skirts and headbands. Different from swimming goggles, professional goggles lenses are made of pressure-resistant TEMPERED glass with "Tempered" printed on it, which is very different from ordinary swimming goggles. Diving goggles have a nasal sac for balancing pressure and can prevent water from entering the nasal cavity. According to the degree of the eyes, the vision corrector can wear a diving mirror that suits him, and it is best not to wear contact lenses. The object seen through the diving mirror underwater is .33 times larger than the actual size. The most important thing to choose is to fit well and suit your face.
2) snorkel
When snorkeling on the water, people can breathe without lifting their heads off the water; In scuba diving, divers can breathe through breathing tubes when resting or swimming on the surface of the water to save air in gas cylinders. From the structural point of view, breathing tubes can be basically divided into two categories: drainage valve type and non-drainage valve type. From the modeling point of view, there are L-type, J-type, C-type, G-type and so on. The length is usually about 42cm and the caliber is 2-2.5cm.
When choosing a breathing tube, it should be noted that the bite should be comfortable, otherwise it will cause mandibular fatigue.
3) Fins
Add a pair of wings that "fly" in the ocean, also known as frog shoes, and provide divers with the driving force to move forward underwater. Different from swimming, diving only relies on the movement of legs to achieve movement, while hands are usually used to do other things (such as underwater photography, manipulating other instruments and equipment, etc.). According to the different use and design, it is divided into two types: sleeve foot type and adjustment type. You don't need to wear diving boots in the foot-sleeve type, you can wear them barefoot according to the number; Adjustable fins need to be equipped with special diving boots.
there are breathing regulators, buoyancy regulators, diving instruments, gas cylinders and other heavy equipment, as well as other auxiliary equipment.
2. Scuba diving equipment
SCUBADiving is "scuba diving", which refers to diving activities carried out by divers with diving equipment such as gas cylinders and breathing apparatus.
1) Breathing regulator
Breathing regulator (for short, respirator) is the key equipment to ensure divers to breathe underwater. It consists of a primary pressure reducer, a secondary pressure reducer and a medium pressure pipe. People can't directly inhale the high-pressure air in the gas cylinder, but need to automatically adjust the high-pressure air in the gas cylinder to a pressure suitable for the diver's depth through the two-stage decompression device of the breathing regulator, and supply it to the diver for breathing. The first stage of regulator made of advanced alloy is used to connect gas cylinders and other equipment; Secondary with a bite for breathing. Many divers are also equipped with a spare secondary.
The second stage of respirator is easy to get into the sand, so it should be specially protected. Once the sand gets into it, it needs to be disassembled and maintained by professionals.
2) Buoy (BCD/BCJ)
