However, what kind of "声韵文字的需要" makes you to "把舐改为舔"?

You don't even know the answer to this question:
"不知JFF在google之余有没有认真想过，此处李用“龙蟠虎踞”与毛用“虎踞龙蟠”的某种必然性与妙处所在？" How dare you talk about "声韵文字的需要"?

Obviously, the excuse of "诗词改成语" dosn't work here. Better rush to the google for the other "N个很好的理由":-)

but don't forget: 把谷歌看了，脑袋拍遍，终难补，大漏勺。
