Because this cup is very important and of unusual significance, it is the mascot of the Qing Dynasty. It can only be used in the early hours of New Year's Day every year, but it can't be used at ordinary times, so it can only be used once a year. Moreover, Emperor Qianlong attached great importance to this cup and personally stared at the production during the production process. This cup was also used by every emperor in the Qing Dynasty.

This cup is the Jin 'ou Gu Yong Cup, which was made by Emperor Qianlong himself and selected 80 craftsmen from more than 3,000 in China. The selection of candidates is very harsh, which shows that Emperor Qianlong attached great importance to this cup. Emperor Qianlong did more than that, even the design of the cup, as well as jewelry and styles, so the cup made was very luxurious and gorgeous.

If this cup is unsatisfactory to Emperor Qianlong, it must be taken back and replaced until Emperor Qianlong is satisfied. The moral of this cup is that it can make the regime permanent. In order to keep the Qing Dynasty going, Qianlong attached great importance to this cup. And this cup can't be used casually, and it can only be taken out in the early hours of New Year's Day every year.

When the emperor uses this cup, he must also write down his beautiful prayers for the peace and stability of the country with a pen. This is what every generation of emperors in the Qing Dynasty should do. In the process of making this cup, Emperor Qianlong issued ten imperial edicts, large and small, which shows how much Emperor Qianlong attached to this cup and was regarded as a mascot by the Qing Dynasty.
