Ahead of the Đoan Ngọ festival, residents of a Ho Chi Minh City alleyway on Phạm Thế Hiển street are working tirelessly to produce hundreds of thousands of bamboo-wrapped sticky rice cakes, known as bánh ú. Production runs from morning until late at night to meet anticipated market demand. The cakes are a traditional food consumed during the festival, which falls on the fifth day of the fifth lunar month. This annual surge in production highlights the enduring cultural significance of the holiday and the associated culinary traditions. The activity demonstrates a local community responding to seasonal consumer needs. The cakes are expected to be popular purchases as people prepare for Tết Đoan Ngọ celebrations.
