It's just sweet soup cooked with cassava root and sugar. However, a hot bowl of cassava sweet soup suddenly becomes a snack on a cold winter day, and a bit of dry golden sunshine makes you feel wistful.
People often nostalgicly remember difficult times. That difficult time has passed for several decades, but sometimes, when startled, they still think it was just yesterday. Cassava and sweet potatoes have become witnesses of that time, with pieces of cassava and rice mixed together.
The reason for eating mixed food like that is because you cannot eat cassava without filling your stomach. The resin of cassava is very toxic, if you do not soak it in water to remove all resin, then when you eat it, if it is mild, you will get drunk like drunk, if it is severe, you will be poisoned. Therefore, just take cassava and cut it into small pieces and bring them with rice to reduce the amount of rice.

A time of sweet potatoes and cassava" is like that. Perhaps, the image of rice grains sticking to a piece of cassava chair has inspired the fragrant cassava sticky rice later.
