So many people buy zongzi instead of buying ingredients to make it themselves. On the one hand, some people can't make dumplings. Not everyone can make zongzi. If you can't make zongzi, make it yourself. On the other hand, the reason is that others don't want to bother, and making zongzi is a time-consuming and laborious thing. Buying zongzi directly saves time and effort. Another reason is that some people really don't have time to make zongzi. For example, they are busy at work and have no time every day, so they buy some zongzi.
