In Cantonese, deuk means chiselling, breaking things into pieces.

When street hawkers sold the candy, it was necessary for them to break apart its original shape with a pair of flat chisels, namely "deuk".

The act of chiselling makes noise and attracts children to buy.

Today, in order to cater to young people's tastes, different flavours of Deuk Deuk Tong are also made, including coconut, chocolate, mango, banana, and strawberry flavors.
