Dear Mr.张，

I'm sorry if I made you guys misunderstand this, but it is a game based on an very interesting experiment, which proved that though the order of the letters is a mess, as long as the first two letters of the beginning and the last two of the end are correct, people can recognize this word without thinking for a long time.

Thanks guys, for replying:). 

But you may have observed that I made many spelling mistakes deliberately in my text. So let's continue in a game mode, exchange the positions of each letter while making sure that others understand what it means ;)

Anmol:

thank you for sharing:)

Thank you for your answer, and I admit that it is really hard to concentrate on language learning like before..
