According to existing research and historical records, Cao Xueqin had not finished writing 'Dream of the Red Chamber'. The first 80 chapters of 'Dream of the Red Chamber' were compiled and continued by Cao Xueqin's good friend Gao E, while the last few chapters were written by another. It was generally believed that the continuation of Zhiyanzhai had added some plots and characters that Cao Xueqin had not written, which destroyed the integrity of the entire novel. Therefore, the ending of 'Dream of the Red Chamber' was not completely certain. There were also different opinions and debates.
