Mr. Dong Zhongli, a member of the Snuff Bottle Association, said that according to the book "Forbidden City Snuff Bottle" published by the "Forbidden City" in Taiwan Province Province, China, the word "ancient" was actually a masterpiece of the general manager of the Ministry of Internal Affairs during Yongzheng and Qianlong periods. Enamel ware appeared in Yongzheng period, belonging to the official kiln products, but Yong Zhengdi didn't think about how to name and inscribe this kind of enamel ware, so he handed the inscription to Wang Hai, then Minister of the Interior. Enamel itself is extremely difficult to fire, and it will burst naturally if you are not careful. When an object with official kiln money is played in the emperor's hand, it naturally cracks, which naturally makes people feel embarrassed. Even if the emperor wanted to get angry, he couldn't start, so Yong Zhengdi wanted to find another one to replace the official kiln money. This style should not only reflect the royal style, but also show the beauty of utensils. Although it was not difficult, it was also extremely nerve-racking, so I handed over the naming and signing to Hai Wang, the head of the Ministry of Internal Affairs. While "Gu" is a fantastic idea when enjoying the moon in Yuanmingyuan, but some scholars find that "Gu" is actually a pun, and "Gu Yue" is a clever way to send a name among them.
