Hahaha and hahaha.
You are really a laughable material. Sorry for the raw honesty but... you saw how poor is the man (Zhang). He claims to be rich but according to what he said, post, behaved, he is too poor to pay you 799,99 dollars.
He even needs to work some paper related low tier job, he had difficulties to pay even 200 Chinese yuans for a month (which is only 27,50 dollars!😂
) and he felt that it is so, sooo, soooooo diffcult to pay Japanese languge course + 200 Chnese yuans...
And you, with what mind, are offeing him 799,99 dollars gymmaxx package?
It's like offering a beggar to buy a golden bracelet.
Or maybe it's just a good joke "The poor Chang is paying 799,99 dollars for bodybuilding!"
If you are joking, I admire 🤣.
