What are the main differences between the old version and the swallow flying in Princess Pearl?

The main difference is that the old version returned to the palace only after the emperor recognized Wei Zi; Before the new edition recognized Wei Zi, Galeries Lafayette returned to the palace.

The new edition adds the main role of the court painter Ben Ming Jie.

When the new version of Galeries Lafayette returned to the palace, May's mother also came back, while the old version of May's mother had passed away.

Some details have been changed and many plots have been added.

The old version, especially the first Princess Zhu Huan, has a lively rhythm. In episode 24, Wei Zi recognized her father, and the new princess Zhu Huan had more details, which lengthened the story, probably because Wei Zi and Swallow had to go through some "hardships" before the truth came out, hehe.
