If you ever received an email from Mr. Song Li, do not be fooled by this person. I received an email from this someone of such name and he was offering huge sum of money. I was doubtful of his motives. Who in the name of Bill Gates, would give such an amount to someone who you do not know or have seen? I searched his name online and it turned out to be a scam.

Try to search his name online and it should yield lots of information about this scam.
Anyway, if someone emails you with a proposal of such kind, then just do a simple online search. If it is a spam in the first place, just delete it then.
