Did the Chinese make a pact amongst themselves to never give out the real recipe for Fried Rice?

Seriously, it makes me wonder. I've tried a lot of "fried rice" recipes from cookbooks, tv, youtube, magazines. Nothing comes close to the fried rice I'm served at fast food/authentic Chinese Restaurants. I mean, you have the key ingredients: rice, egg, vegetables, chicken/shrimp/pork, spring/green onions, but there's always something missing. It never tastes the same as the ones they serve in restaurants. Is it a Chinese secret? =PDid the Chinese make a pact amongst themselves to never give out the real recipe for Fried Rice?
Probably because chinese people are generally better at cooking chinese food because they cook it all the time. Did the Chinese make a pact amongst themselves to never give out the real recipe for Fried Rice?
You know, this is really true.
