Never seen them in Beijing, nor Tianjin. I can't tell if they are only local to Guangdong.
I was told not to eat many of these. I didn't like the smell, though.
Zongzi is a traditional Chinese food, made of glutinous rice stuffed with different fillings and wrapped in bamboo leaves. They are cooked by steaming or boiling. These were, I guess, filled with salted pork.
I'm leaving Guangzhou in two days. I had amazing time here, enjoying the warm (and hot)weather, enjoying the green enviroment. As for the food, I guess I'm used to Tianjin's, the Cantonese cuisine is a bit sweeter than the one up north. I mean, it's all habit.
Have a lovely start to new week and month!
