5 kg of glutinous rice can generally pack about 50 zongzi. Precautions: Soak the glutinous rice for 3-4 hours in advance when making zongzi, which will not only make the glutinous rice fuller, but also make the glutinous rice expand more in the process of cooking zongzi, but you should not put too much glutinous rice to avoid the glutinous rice bursting the zongzi leaves; Eat zongzi in moderation to avoid indigestion caused by eating too much.
