Why did director Lin kill Ding Meixi in a hidden corner?

In fact, it is not that Director Lin wants to kill Teacher Ding, but that he wants to kill Teacher Ding, that is, to instruct Director Lin to kill him, that is, to be impeded.

After the wine-persuading incident, Director Lin insisted that you should not think that your money could block my mouth, but you were timid in front of the photos and finally promised to help Lin Yan get them back. At this moment, the two men have been completely torn apart and cannot make any progress intellectually. Their last deal was to exchange photos with Ding Meixi, and the significance of photos to director Lin was to muddle through. Ding Meixi fled with her daughter, and when Lin Biao recovered her, Lin Biao had already moved to kill her, so it was Lin Biao's original intention to let director Lin kill Ding Meixi.

While playing the harmonica, Lin Yan thought that Ding Meixi was dead, so she shed sad tears. Killing Ding Meixi is Lin Yan's request, and cruelty (dismembering and destroying the body) is director Lin's free play. Seeing all kinds of tools and skilled operation is obviously director Lin's personal preference.
