How did Erkang come back from Myanmar?

Swallow, Wei Zi's good sister, was very sad, but she went to Myanmar with Wei Zi to find Erkang. Erkang knew that Wei Zi would come to him in his sleep, so he always wanted to see Wei Zi in his sleep. Later, after Erkang got well, he wanted to leave the palace in Myanmar. On the day of the Songkran Festival, Erkang left the palace and met Wei Zi.
