Before the trip, I set up the goal of this journey. Although I got lost and confused sometime, I always remember those original intentions, which are "Be humble and learn", "Open, and talk with people", and "Observe and think." In the end of this trip, I realize that I am much stronger and brave enough to face any future challenges, which is not because I studied a lot or some boring answers, but because I've met so many interesting and smart people. They've taught me words of wisdom and stayed besides me in my hard times. Again, I really appreciate it.
