Knowledge card: artistic signature, also known as "signature design", is the beautification and artistry of personal names. It is not an invention of modern people, but it has existed since ancient times. The predecessors called it "Flower Charge", which is similar to Flower Charge, and there are other names, such as Flower Charge, Money Charge, Signature Charge and Agency Charge. These appellations have similar meanings, and all have the functions of expressing identity, responsibility and trust, so they become vague and often mixed. The same is true today, except that the word with "pledge" was discarded and used as "signature" and "signature". Now all we have to do is mention "signature", which sometimes means "artistic signature".
