A little birthday greeting from Gui Gui to Aaron just made my day~
Here is the post on Weibo:

 
Translation: (this is the little text box w/ the pic) @ Gui Gui Wu Ying Jie:  Being able to know you is really a wonderous and special... Its your birthday (cake) wish you lots of happiness on your birthday! keep using your songs (singing voice - more literal translation) to touch many more people, ok? @ Yan Ya Lun

Aaron's response (to Gui Gui's) (the line near the text box, not the first one) // @ Yan Ya Lun: How wonderous, how special!? I want to know ^^! Thank you Gui Er ( then the two emotions, they actually blow a heart) 

The lines before it, were response to a post from the actress who played Teacher Angel in PiLiMIT :) 
here is the translation for that too :) 
// @ Teacher Angel (not really what it says but idk the actress's name) : During MIT, I remember an except of your filming behind the scenes (tanslation is not quite accurate here), and I believe in that confidence from that time's answer. You will continue to be famous and passionate (little icons that say "gives strength" , the the cake) 
Aaron's response: I really enjoy the stage right now, MIT is also a furfillment in my heart forever (by furfillmen i mean to say something that satisfies him, kind of hard to translate)
