Hello quyichuan1 - Welcome to Pherotalk.
No, it is not unusual at all for us to see Asian people posting here - There are many members from all over.
If you have a read of this thread:
https://pheromonetalk.com/t/how-do-i-qualify-for-a-25-gift-certificate/19934
And give us a bit more info, you will earn a GC and give us the sort of info that will help us offer better advice. 
In the meantime, the start of this thread has links to all the basic info on choosing and using pheros:

Also, if you have a look round the forum, you will quickly see there are certain issues related to phero use and Asians. Generally this takes the form of a greater sensivity to Androstenone when compared to other races. However, there are plenty of very effective alternatives and you might want to consider the social products like IG, IO, IH and Instant Shine for starters to see how you get on - then maybe add-in small amounts of none to see how it goes.
Don’t let the name “Social” put you off - These pheros are just as powerful and effective in signaling qualities that stimulate attraction - Which is of course a lot more than just making someone feel horny.
Hope you see good results soon.
