How did the "Ding" of cooking become a national symbol in ancient times?

Ding, at the earliest, was only used in cook the meat in ancient times. In the early days of social development, people only cared about food. There is an old saying that goes well? The country is people-oriented, and the people take food as the sky? . This shows how important food and cooking tools are. Dayu was deeply loved by the people after his meritorious service in water control. Shun also complied with public opinion and passed the throne to Yu. Dayu, who was deeply loved by the people, founded the Xia Dynasty. There are still many courtiers who refuse to accept it, so they ordered people to cast nine cauldrons, symbolizing nine states, namely Yanzhou, Qingzhou, Yangzhou, Xuzhou, Jingzhou, Yuzhou, Liangzhou and Jizhou. This Jiuding is a metaphor for the prosperity of the country. This move shocked the unconvinced officials who had to take orders from Dayu. After Shang Dynasty, Ding gradually became a sacrifice, and bronze was the most needed to make Ding. Bronze at that time, like steel now, was a expropriated resource. It is also for dignitaries to show their lofty status. Muswuding, the son of the king, built this tripod to worship his mother and express his thoughts on her. This tripod is one of the largest bronzes among unearthed cultural relics. In ancient times, people believed in the gods very much, and the tripod became the utensils of those gods and the bridge between the emperor and the gods, and its status immediately became the supreme glory. In addition, the size of the tripod is dominant, covered with exquisite patterns, which fully embodies the powerful smelting level and casting skills of the Shang Dynasty at that time and shows the powerful war strength to other countries. At that time, the raw materials of weapons were mainly bronze, such as knives, bows and arrows, spears and so on. Whoever has a hard fist in any country has the capital to speak. Envoys from other countries come to Korea to pay tribute, which is essentially to test the military strength of this country. The tripod carried out at dinner is to show them their military strength and hit other countries horizontally, so don't bite off more than one can chew.
