In this trip, each of us has a buddy, and our buddies were from Harbin Engineering University.

​

During the trip, we had organised an International Student Ball for them. We were dancing, chatting and interacting with them. It was an unforgettable night. Also, we went out for dinner so we can familiarise with each other. 

​

After all these gatherings, we had built up an intimate friendship. And this made me understand the importance of interpersonal relationship.
