Describe what you will do to get ready for a festival such as Mid-Autumn Festival and/or what you will do on that day? For Example: (Tet) The preparation for Tet holiday is taken place very soon because it requires many steps. All members of families clean and redecorate their houses together. Then, they buy food, drink such as cookies, sweets, candied fruit, melon seeds...to offer their guests and to store because in this occasion, many shops are closed. A branch of peach flower or a kumquat tree cannot be absent from every home during these special days. Children are the most eager, as their parents will buy them new clothes. In addition to buying things, many Vietnamese families make Chung cake, pickled onion, frozen meat, which are our country's traditional food on Tet holiday. We decorate ancestral altars with a five-fruit tray, vegetables, sweets, and flowers.
