From then on, Nana starts to behave unconventionally and unrestrainedly.  She flirts with every man she meets till the end of jumping bed with them.   In the graveyard, when she is with Xiao Bo to pay their respects she wakes up to reality.  But nobody knows if she could find a man who would like to live with her or not.

信仰基督的冬冬来到教堂，却既未忏悔也没领圣体。他只是把自己的一个十字架送给了素不相识的小博。小博回到家里，朗读了一段有关“准天使”的寓言。寓言上说，人虽不完美，但仍旧可以成为别人的准天使，把别人送入天国。

As a Christian, Dong Dong goes to a church.  There he neither repents nor takes the bread and wine.  He only gives his cross to Xiao Bo whom he never met before.  Xiao Bo goes back home and recites one piece of fable about “Demi-angel”.  In the fable, it says that although human being is not perfect, still can it become the demi-angel of others’ and send them to the Heaven.
