Why do people have different views on Princess Zhu Huan?

Before I saw Princess Zhu Huan, I thought that people like Swallow, it was estimated that only girlfriends like Wei Zi could stand her and be willing to tolerate her, but now looking back, I began to wonder whether Wei Zi really regarded Swallow as a good sister. Do you remember the story that the swallow went to the hunting ground to look for crape myrtle? Ziweiming knows that going to the hunting ground is extremely dangerous, but he still has to let the swallow take risks for himself. He really doesn't care about the swallow's life and death. It's terrible to think about it. Later, both of them became a space space. The emperor asked the swallow to practice calligraphy. Swallow was originally zero-based, and writing words is already very good. However, Wei Zi not only didn't encourage her, but also laughed at her ugly handwriting and tore up the words that the swallow had worked so hard to write. You know, the swallow had to take it to the emperor the next day, so it was torn up by Wei Zi. It's really irritating to think about it. It always felt that Wei Zi didn't really want to swallow it.
