My experience in participating in various team building activities or events has been excellent and memorable. As I got opportunities to work with a few reputed and large organisations with active operations team, such events were frequent.

Fortunately, I had the chance to experience both indoor and outdoor team building activities from the entry level to manager level. Those were thrilling experiences and all the team members had a lot of fun. In indoor games, I remember to have participated in every kind of games possible such as mine field, tag team, truth & lie etc.

I found the outdoor team building activities even more exciting. We played tug-of-war, shooting paint balls, shack race, relay race etc. The most important takeaways from these games were the cordial relationship and bonding we team members developed. Those activities had a very positive impact on our overall team performance.

My dear family has all 4 members: Mom and Dad, sister, and me. My father’s name is Nhat, he is a construction engineer. Every day, most of the time my dad is at the construction site. Because of that, my father’s skin was dark. When he came home at night, he often went to play soccer with his friends at the football field near him. Speaking of my mother, my mother is 40 years old, she is also very busy. My mother is a nurse, so most of the time she is in the hospital. My sister is Trinh, 22 years old. She is a beautiful girl with a very charming smile. Because my parents are often busy, nee-san takes care of me and cleans the house in place of my parents. When I finish school, I often help her sweep the house or pick up vegetables. Although we’re busy, we eat together almost every night. After dinner, we watched a comedy together and told each other the story of today. I am very happy and happy to have such a family
