Neighbours said they first saw the raging flames in the store right after midnight.
They screamed and banged the door to warn the people inside.
The father, Tran Thanh Tam could escape the fire with his five-year-old daughter. However, the mother and her six-year-old son were trapped inside the store.
The fire spread quickly. Although 50 firefighters and 4 fire engines arrived soon later and controlled the fire, almost everything inside was burned down.
Police are investigating the cause.
