You asked for backup and asked me to send Li Yongle's

Distribute the electronic version of Mathematics 100 handout.

One for you.

Since you are a person with financial difficulties at home,

But I still grit my teeth and work hard.

Man, a good boy who insists on self-study, is worth it.

Get the attention and help of our caring people!

I'll e-mail it to you,

I hope you can give me your relevant information.

I wish you progress in your study!
