I like spring most. I’m joyful and happy every new year coming. May be boisterous air of spring always bring full vitality feeling to everyone.

Spring has tree in flower, bird in twitter, everyone in new clothes, everyhouse in new repaired. Tet is an important event of spring, it is an occasion to those who work far from their house/ country be able to get together in family.

They forget the past diffcult things, the unlucky chance, and of course they are willing to send many wishes together. They always pray for health, work, happiness.
