Its really Xue Ping

Song Yan took the stack of documents and thanked Assistant Xi who took his leave after he was done delivering the documents. Song Yan asked him to stay, and Assistant Xi told her that he was needed at the office. 

Of course, Song Yan would not keep him with her when he was busy and let him take his leave. Once he was gone, Song Yan flipped through the information that Fu Yu Sheng had collected on Xue Ping and she had to admit that she was surprised when she saw that Fu Yu Sheng had not only found everything about Xue Ping when she married Master Yi but also when she was a child. 

It included not only information about her living in a small village which was far from the city, where she used to work and how she slowly rose to prominence but it also mentioned the kind of men, she dated. Song Yan was not even surprised that Xue Ping only dated men who were rich and influential.
