i want to know all the traditions and culture of all countries but..............

I hope that you will go traveling with your family to different countries in the future. You might find the culture similar in some countries in Asia. It might be fascinating for you to meet the local people, find out about their culture and learn about the tradition. I found it fascinating to meet the Masai Mara tribe when I was in Kenya. In Guatemala I found the Mayan history fascinating. In Israel I gained a greater understanding of religion. Almost every country in the world is interesting in its own way. I wish you and your family happy traveling for the future.

The same to me! To communicate with people from other country is really charming.However,even China's customs are a longlife time to learn about.
