There are two small regrets in the ending of Princess Lanling, mainly to illustrate two different story endings. One confessed the ending of Gao Changgong and Yuan Qingsuo, and the other confessed the ending of Yu Wenyong and Yuan Qingsuo.
The two poor people are not the same person. Gao Changgong's little pity behind him is real self-pity, while Yuwen Yong's little pity behind him is Yuan Qingsuo's pretended self-pity. The two stories have different plots, so they have different endings.
