Funny scene from yi fang ban ting yi shui gang last ep:
"Wo zhi dao. Wo she me dou zhi dao!"
"Ni bu zhi dao! bu zhi dao!"
"Wo zhen de dou zhi dao le! Wo zhi dao~"
"Ni she me ye bu zhi dao! Bu zhi dao.."
"Wo zhi dao!! Wo zhong yu zhi dao le.."
-Female lead mumbles something then goes "Bu zhi dao" again
"wo zhi dao~!!!"
"Bu zhi dao bu zhi dao bu zhi dao bu zhi dao bu zhi dao bu zhi dao bu zhi dao!!!!!!!"( While crying and going ballistic then whacking the guy's chest and then crying there)
Okay it was supposed to be emotional at all but I just started laughing like crazy cause Dingyi looked like a duck and the I-know-I-don't-know thing was super hilarious kwakwakwa
Anw, zhi dao means I know and bu zhi dao means I dont know.
