A Song of Shao Huaxue (Master and Apprentice)

I was not born before you were born, but I was already old when you were born. I am far away from you, but you are separated from me by the corner of the ocean. I was not born before you were born, but I was already old when you were born. It turns into a butterfly to look for flowers, and roosts on fragrant grass every night. You were born before I was born, but I was born before you were old. The master used the Yuanyang Sword, but more than ten years later, he had never seen her use it, and the other half of the Yuanyang Sword was not him. National hatred and family hatred, old friendship and true love are the biggest obstacles that test the master and apprentice. However, suspicion also separates them both.
