What is the pinyin for "carrying a schoolbag"?

1, suddenly I saw an Indian teenager carrying a backpack rushing to help him, and all the passing cars stopped to make way, and finally saved the day!

Summer vacation is a treasure. When you are in a good mood, you don't have to read a book every day, you don't have to go out and carry a bag, you can sleep late. Occasionally, text messages bother you, just to say hello. By the way, it's sultry and sweaty in summer, and I often wash my pig's feet. Happy summer vacation!

3. When the summer vacation comes, put on your schoolbag and run home in groups of three or five. Watch TV, play computer, upgrade weird. Do your homework quickly and well, and exercise your wrist and brain. Doing housework is diligent and good, and your mother praises you as a good baby. Happy summer vacation!

I was kicked out when I went today, and let me go with my schoolbag on my back.

5. At 5: 20 p.m. that day, the reporter found in Xuwang Internet Cafe, Dongmei Internet Cafe, Golden Triangle Internet Cafe and Yuandian Internet Cafe in Dongsanyao Village that there were primary and middle school students coming in and out with schoolbags from time to time.
