Zhao Jiang Dawn, who's the killer?

The murderer may be Li Xiaonan, so far, she is the most suspect.

In Zhao Jiang Li Ming, there are many fogs about who killed Su Rui. First, Song Hu beat Su Rui by the river and threw him into the river. Song Hu went to barbecue. Then Su Rui climbed up again, and then went to the hotel to meet Yu Hong. Thus, Song Hu is not the murderer of Su Rui. Yu Hong is Su Rui's lover. Yu Hong has no reason to kill Su Rui, nor should he be the murderer.

Li Xiaonan clearly knew that Su Rui and his colleague Yu Hong had proper relationship, but pretended not to know. This gift is very profound. When she realized that she had been entrusted with inhuman behavior, she filed for divorce, but in exchange for cruel domestic violence. She also learned that Su Rui had tried to commit suicide many times and defrauded insurance claims.

Finally, on the night of the murder, she sent a short message to Song Hu with Su Rui's mobile phone, asking Song Hu to go to the river to make others mistakenly think that Song Hu killed Su Rui, which seems to be looking for a scapegoat for herself.
