With reports that Facebook and Baidu have reached a deal to start a Facebook-like social networking site in China (the deal is still pending), Eric Jackson points to some important lessons in how Mark Zuckerberg has been doing business in China.  Jackso, who writes the Tech and China blog for Forbes, says Groupon's Andrew Mason, among others, could learn a lot from Zuckerberg.  Zuckerberg understood that getting into the China market had to be a top priority for Facebook, so he made it a top priority for himself.  And Jackson says these are the four main takeaways from how Zuckerberg approached the market:

1) Know what is important and what isn't important.
2) Don't delegate what's important.
3) Don't kid yourself that you're funny when you're not.
and 4) Show a little respect towards others.
