According to the identity of inscribed tablets, imperial tablets can be divided into emperor tablets and provincial, state and county officials tablets. The emperor inscribed a tablet, which is a symbol of the royal family. It is supreme. If an official passes by, he will bow to it. If the person who wrote the inscription is not only a top scholar, but also a senior official, it is also extremely precious. According to the main identity, it can be divided into champion, scholar, juren, gongsheng, scholar plaque and so on.
Similar to the plaque, only the emperor's royal approval can have it, not about rank, but about merit. Sometimes even armor doesn't necessarily have the emperor's carved dragon tablet.
