Thanks aitap. Honestly, I can't self determine am I asking XY question. If I am asking Y for X, at lease at the the moment I was posting, I believed that I was asking X. Moreover, what is X and which is Y is quite depends on how the reader understand the question. Thaz what I am still learning to understand.
However, I've so realized that I am putting this question badly. I've tried to rephrase it in this reply. I hope, if you don't mind, please teach me if I am asking the right question this time. Thanks again! =)
