As I sent a mail that mentions the title of a textbook and I don´t see it, I would like to know if it is forbidden to do those things. Greetings.

Yes, it is forbidden to send emails.

Who did you email?

Welcome, Maggie! There is nothing preventing you from mentioning textbook titles in emails to us.

I've searched my inbox for emails containing the name "Maggie" and I don't see anything matching your description. Feel free to copy and paste the contents of your original message so that I can address it here!

The dialogue appears in this page.

First sentence: "Lǐ lǎoshī, xīngqīwǔ wǎnshang nǐ yǒu kòngr ma?"
Dear Sir

Here is my recommended procedure for on-the-go pinyin romanization:

1. Go to MDBG.net.

2. Click "Look Up All Chinese Words in a Text" on the right hand side of the screen.

3. Paste whatever Chinese text you'd like the pinyin for in the box provided, and click "go."
