I just graduated for a year and live with my parents. Can British tourist visas use their asset certificates and property certificates? What materials are needed to prove kinship?

No, travel must have a certain fee in your name. If it's all in your parents' name, it's useless. After all, they are not going to travel. So be sure to deposit about 5W in your name (depending on the number of days). Of course, you can also use their assets to prove and notarize your relationship with them to assist your materials, but this is only an aid, and others will still see how many assets are in your name.
