What does the end of Beijing 8 1 mean?

The housekeeper accused Xu Ruoqing of extreme feelings and lines, which made everyone feel that the housekeeper was sick and loved the third young master. As a matter of fact, it is true that the housekeeper is ill. He was a victim of the feudal old society, honest and ignorant, and resolutely guarded the haunted house No.81after his family was ruined. He didn't know that the third young master was still alive, but later he came back, but he hated it because of Lu Diyu's bleak fate.

There is also a third young master, who has been waiting for Lu Dieyu all his life, so when he saw the near-term reincarnation of Lu Dieyu, his wish came true. He was shocked and went to the place where he should go ... (I thought that Yan Jiansheng of The Scholars must watch two lights before he died) But this passage is very strange, but it is also very touching. Are victims of love in feudal society.

Wu Zhenyu actually loved Xu Reqing, but she didn't betray her.
