if Ma does not like the way, he can learn from 罗曼 :)

Just come to the US. If he decided to accept the rule to play, then follow the rule play it. The rule you imagine may have tons of problems. At least so far they did pretty good. In other words, their way, you may not like it, has been proved effective. How do you know the way/rule you generated in your brain will be as good? Ma needs to learn to be professional.
