Hi Lam , This Tet, our family had a great time! We cleaned and decorated the house, cooked banh chung, visited relatives, exchanged New Year wishes, and received lucky money . My parents love gathering with the kids, and I look forward to good wishes and red envelopes. It's a wonderful time for the whole family to reunite and welcome the new year. How about you and your family?
