Why the Chinese people in Malaysia prefer to give Math and Science tuition, rather than giving Kung Fu lesson?

like in China.|||because kung fu when you get old you cannot use it anymore, with math and science you can use it until you die|||Because Math and Science are universal subjects whereas Kung Fu is a hobby or extracurricular activity which is non-scholastic. There are no jobs with Kung Fu requirements except for competitions.|||Baka! Chinese people in China give English, Math, Science, etc tuition. Kung fu lesson is a personal choice, NOT a formal requirement.|||Because they prefer education over martial arts. That's a good thing, no?|||because education can bring you somewhere, where else kung fu is just a hobby ! i guess ..
