Who is the role played by Jin Suoxuan in the Korean drama Ghost?

The role played should be Nan Zhu's wife, but judging from the honorific title given to her by the male host, it should be Weng Zhu, mostly Wang's sister.

While watching this play, I thought Jin Suoxuan would be the bride of the ghost, but I didn't expect to get a lunch with an arrow. It was a pure guest appearance, but under the beauty, the later hostess was somewhat eclipsed.
