1. Soak the glutinous rice in advance, which will make the glutinous rice not so hard. If the glutinous rice is too hard, the wrapped zongzi will not be sticky or glutinous enough, and the taste will be affected to some extent. Therefore, it is recommended to start soaking the glutinous rice one day in advance when wrapping the zongzi, so that the made zongzi will be soft and glutinous.

2. Cooking time: Fully cooked glutinous rice will be softer and more glutinous, so when cooking zongzi, it must be cooked for a long time. Generally, it is recommended to cook for at least three hours.
