Cantonese people eat everything. How did this stalk come from?

Guangdong belongs to Lingnan Mountain area in history. Before it was developed, people lived in poverty. They hunt wild animals in the mountains and catch insects to eat in the fields. Later, with the development of the region, everyone's traditional way of life will still be preserved. Although it is not widely accepted by foreigners, it is more Lingnan culture for Cantonese. So in everyone's laughter, Cantonese people eat everything.
