How did Sister Ling go crazy in Big Times?

Xie said that if anything happened to Ding-Xie, Fang's family must watch. As a result, Fang Min was the first to die because Ding Yi jumped off a building. Later, Ding Xiao gave everything to Rockett. After Ding Xie was sentenced to death, Ding threw Fang Fang and He downstairs. Zhanbo Fang grasped the iron shelf and didn't fall. However, Fang Fang and Fang Ting were killed. Lingjie saw this desire with her own eyes, but she could do nothing. She can't save two sisters. In a rage, she drove to kill four Shi Ding brothers, but it didn't work. She also hurt her head. Under such a barrage of blows, Lingjie finally couldn't bear it and completely collapsed. When I saw her again, I was crazy.
