Oysters and Luoyang Bridge
One of the four ancient bridges in China, quanzhou Luoyang Bridge was built when the northern Song Dynasty minister Cai Xiang was in charge of Quanzhou, Quanzhou as the first large port, there are many commercial trips, but it is blocked by the Luoyang River, you have to cross the river by ferry, but the Luoyang River tide is dangerous, the merchants crossing the river will be dangerous to life, and building a bridge has become a top priority.
The site of the bridge is located in quanzhou Luoyang River into the sea, because it is located in the harbor, the waves at high tide, the stone bridge is difficult to establish a foundation, Cai Xiang and others brainstormed, painstakingly thought about the method of building a bridge, and finally had a plan, first throw boulders under the water, lay an underwater long causeway, and then lay horizontal stones on this embankment, which is the "raft-shaped structure" that later generations relished.
After the bridge was completed, everyone worried that after a long time, the bridge would be damaged by the tide, and Cai Xiang thought of oysters, and the "Song Shi Cai Xiang Biography" said: "Xiang Lishi is a beam, its length is three hundred and sixty zhang, and the oysters are planted in the foundation to be solid, and they are still relied on."
Oyster pups can swim in the water, and once they find a rock that can be attached, they settle down, catch the oyster pups, plant on the piers, and within a few years, the oysters will be layered on top of each other, and the tide will be difficult to shake.
Cai Xiang also ordered that oysters should not be predestined, and by the time of Emperor Shenzong of Song, the Quanzhou magistrate had even legislated that those who caught oysters near the Luoyang Bridge would be imprisoned for two years.
The cooperation between people and oysters has entered a honeymoon period here, oysters help people guard the bridge, people no longer prey on oysters, Luoyang Bridge can stand in the tide for thousands of years, thanks to the work of oysters.

Healthy and safe eating recommendations
First, do not eat offal
Pollutants such as heavy metals tend to accumulate in the visceral mass of shellfish organisms, while heavy metals in muscles are the lowest. Therefore, only the muscle parts of shellfish can be eaten. Looking at color is the easier way to judge. After opening the shell, the slightly blackened pieces of flesh are mostly offal clumps. Some shellfish have a black sand line inside and cannot be eaten.
Second, pick the shell smooth
Compared with the appearance of pimples of oysters, scallops, etc., the appearance is clean and smooth, there are fewer dirty things attached, and the corresponding pollution is also less.
Third, soak in brine and heat thoroughly
Before cooking, put the shellfish in salt water for a period of time. This helps shellfish expel all kinds of toxins and sand. Then, carefully clean the surface of the shell with a small brush. Cooking methods are preferred to steam, boil, etc., which can thoroughly heat and kill bacteria.
When processing, it is necessary to put cold water under the pot to ensure that the internal and external raw and cooked degrees are consistent. The method of grilling is easy to cause uneven heating, external cooking and internal growth, it is recommended to use less. ■
