In my opinion, customs and traditions are very important. Like other families, we have our own customs and traditions.

Firstly, these's custom in our family of spending Sundays together. On Sunday, we always go out. Sometimes we go on a picnic in the park or a near by beauty spot.

Secondly, these's a tradition that we make chung cake and cook braised pork and egg. Chung cake it's short and square. Braised pork and egg is our tradition dish for Tet. It's so delicious!

We all enjoy these customs and traditions because they make family member closer and love each other more.

Travelling helps us to achieve this break. At a new place, one is curious to know and eager to gather all the unknown information about the place which he has neither read nor heard before he gets thrills and surprises which keep the interest and enthusiasm alive and encourages us to keep our journey on.

While travelling, one comes across a number of people from varied backgrounds and places. By interacting with them, he comes to know about their heritages also. In case one has psychological bent of mind, one increases one’s experience and power to understand others. Understanding human nature is, perhaps, the best part of education. Travelling satisfies all demands of a good hobby – it is absorbing education and refreshment to the mind, body and soul.
