Zhu Shazhi, an online buzzword, refers to those who can't get it and can't forget it. From Zhang Ailing's novel Red Rose and White Rose: "Maybe every man has had two such women, at least two. Married a red rose, over time, the red one turned into a touch of mosquito blood on the wall, and the white one was the moonlight in front of the window; When you marry a white rose, the white rose is a grain of rice stuck to your clothes, and the red rose is a Zhu Shazhi in your heart. " It seems that there are always people in life who miss it but never forget it. In fact, it is an irony for men to like the new and hate the old. Eason Chan's Red Rose and White Rose also quoted this meaning: "What you can't get is always in turmoil".
