What does this phrase mean?
qin ai de wo kan bu dong you.

Question

Answer

Hi ChefW...i think it's...the Chinese Pinyin...the Chinese sentence is"亲爱的我看不懂你“。
which means "I do not understand you my dear"

Answer

Hello ChefW,

Yes it is definitely Chinese as Aileen mentioned.
其奈的我看不懂你 
qinaide wo kanbudong ni 
qinaide = dear 
wo = me , my
kanbudong = unable to see ( understand)
ni = you 
It means:
"My dear, I am unable to understand you."

In your sentence the English word 'you' is used instead of Chinese 'ni'.
