对误用了"Jap"一词道歉! Apologize for the word "Jap"!

前几日在我公开的问题中用了"Jap"一词. 后来日本朋友告诉我对日本人来说这是非常不礼貌的措辞, 对此公开道歉! 非常感谢这位日本朋友对我的帮助,也请您原谅我的无知, 再次抱歉:)
Several days before, I used "Jap" in my open question. One of my Japanese friends told me this word was really really impolite for Japanese. As a result, in order to express my aplolgise I wrote this. Appreciate my Japanese friend as well as please forgive me:)
