VOV.VN - In recent days, households in Tranh Khuc, on the outskirts of Hanoi, have been working at full stretch as Tet approaches, mobilising entire families for every stage of making banh chung (square sticky rice cakes traditionally prepared for the Lunar New Year). The annual peak production period typically runs from the 20th day of the twelfth lunar month through the full moon of the first lunar month.
