In the thread you want to reply in, click on "quote" on any reply.
In a new tab, find the post you want to quote, and click on its title to reload the page to that specific post. Then copy the message number (last 8 digits) from the URL.
Go back to the original tab, and paste over the 8 digits after "quote=" with your new 8 digits. Press enter.

In Final Step:
[quote author=theymos link=topic=4144474.msg5473531#msg5473531 date=1393807509]
We need change code topic=4144474 to topic=497545 right?
Because if we not change it, when someone click link quote they will be not on target post by theymos.
