Songti is a Chinese font that seems suitable for printing. The strokes vary in thickness, generally horizontal and vertical, with decorative parts at the end (namely "feet" or "serif"), and strokes such as dots, strokes, strokes and hooks have sharp points, which belong to white body and are often used for text typesetting of books, magazines and newspapers. Because it was introduced to Japan from the Ming Dynasty, it is also called Ming style and Ming style. Song style is a printing form, which was born in block printing and formed in Ming Dynasty. In recent years, there are rumors that it was created by Qin Gui, which is groundless, neither recorded in historical materials nor supported by literature. However, in the existing literature, it can be clearly found that imitation of Song Dynasty and Song Style were both formed in the bookstore. After the Song Dynasty was defeated by the Jin Dynasty, people thought that the books left by the Northern Song Dynasty were reprinted. Many publishing houses were established on Pengbei Street in Lin 'an, the capital of the Southern Song Dynasty, including Chenzhai Bookstore in Chen Qi. The books published by Chenzhai Bookstore have distinctive regular script fonts. This kind of font, copied by later generations, is the so-called "imitation of Song Dynasty" in modern times, which has become the basis of Songti characters.

Insurance policy, referred to as insurance policy, refers to the written proof that the insurer and the applicant sign an insurance contract, which is the main form of signing an insurance contract. The main contents of an insurance policy include statements, insured items, exclusions, conditions and other matters. According to China's Insurance Law, the establishment of an insurance contract does not depend on the issuance of an insurance policy. As long as the insured and the insurer reach an agreement on the terms of the contract, the insurance contract is established. Even if no insurance policy is issued, the insurer shall be liable for compensation. Unless the parties to an insurance contract agree in the contract that the insurance policy is the effective condition of the contract. The insurance policy must clearly and completely record the rights and obligations of both parties. The insurance policy mainly states the names of the insurer and the insured, the subject matter insured, the insured amount, the insurance premium, the insurance period, the scope of liability for compensation or payment and other specified matters. According to the applicant's application, the insurance policy is signed by the insurer and handed over to the insured. Insurance policy is the main evidence for the insured to claim compensation from the insurer when he suffers losses due to an accident, and it is also the basis for the insurer to collect insurance premiums.
