度娘的心只许给他
[dù niáng de xīn zhĭ xŭ jĭ tā]
'Du Niang (the nickname for Baidu's search page girl character) Allows Her Heart Only To Him.' Du Niang originally refers to.baidu.com's logo character, which becomes an embodiment or idol here to signify loyalty toward an ideal love - allowing your heart solely belong to that special someone.
