A netizen said, when he was a freshman, there was a classmate in his dorm who came from a poor family, and even in winter, he still wore a thin jacket.

He wanted to help him, but was afraid of hurting his pride.
So he told his mother about it, and his mother said, leave this to me, you can rest assured.
A few days later, his mother sent him a down jacket, and called to say, there's a sale at the mall, I think it's cheap, so I bought one for you.
He happily tried it on, but it was too small; he's tall, and that classmate is short.
He called his mom to ask, and his mom said, it's on sale, very cheap, just wear it if it fits.
After hanging up, he joked that his mom was being cheap.
Then he asked other classmates, hey, can anyone wear this? Try it on, try it on.
Everyone looked at the length and tried to see if it fit that classmate, and it was just right!
Isn't that perfect? It was bought according to his size.
He said, here, you can have it, I can't wear it anyway.
That classmate said, okay, I'll pay you.
He said, okay, fifty yuan.
That classmate agreed, and they bought it.
The down jacket cost 280 yuan, and the male classmate wore it for four winters in college.
