Do I need to buy an extra bowstring to buy a bow?

When buying a bow, you need to buy an extra bowstring as a backup.

Know how many (thick) bowstrings you need. This value is related to the selected string material and the tension of the bow. A high-pound bow needs thicker or more strings to support this weight, while a lighter bow needs fewer or thinner strings. You need to consult the manual, or you'd better consult the equipment store to determine the number of shares you need. Note here that the number of strands or the thickness of bowstring needs to match your tail. If the thickness of new strings changes, you may need to put on a new batch of strings. )
