數下下面四句英文有幾多個“F”字！

記住只可以數一次呀！


FINISHED FILES ARE THE
RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE
EXPERIENCE OF YEARS


攪掂未？

數完先好睇下面呀…






有幾多個呢？

三個？














錯啦！有六個呀！唔係講笑架！


試下睇多次：


FINISHED FILES ARE THE
RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE
EXPERIENCE OF YEARS

個原因係好深入既…

我地個腦係唔可以運算個“OF”字！
好難相信？
如果有人數到有六個“F”，咁佢真係好掂！
放心，數到三個係正常既！
