I think Tet holiday is the most important celebration in Vietnam because it is an occasion for family-reunion, for human love and for better hope. All of us seem to forget the hatred, bad lucks and then try to be nice with others. Everyone is eager to take part in many special activities, which are expected to bring good lucks and success in the New Year. Tet is also the time for us to relax and enjoy our special foods, warm family atmosphere after a hard-working year.
