Practical Experience: I got up at 5: 30 on the morning of the 12th, because I had to gather in front of the public health building at 6: 30. This was the earliest time I got up in my college life. It was really a challenge! But I understand that the challenge is just the same as ours.

Coming, we will eat the bitter, do
