=>Tuesday, February 1

. My family usually has a day off on the 28th of the New Year, so my parents often go to buy peach branches and kumquat trees on this day.

- Why it takes place?

=>Lunar New Year is a typical Tet holiday and depends on each country

- What the people do during this festival?

It is said that on the 1st of the Father's Day, the 2nd of the Mother's Day, and the 3rd of the Teacher's New Year, but in my place, all of my relatives celebrate in one day. Thus, my parents have time to congratulate colleagues and superiors
During Tet, there are several customs that make Tet a unique festival. For instance, adults tend to give lucky money to children, visit friend and relatives’ houses, play cards, and going to churches, temples or pagodas to make good prays for their family.

This is an important festival to us. Vietnamese take this day as an important festival day. In our tradition, we start the year with the hope of eliminating the bitterness and failure of the past year and start a fresh year with the hope of fortune and happiness. Furthermore, this is the time for families and relatives to stay together under the same roof for rekindling love and bonding.
