Yes, Tang Rao gave A Ji a surname, and the choice of the surname Qiu is taken from the upper half of the character "Yue."
During his time in the Nine Realms and the Seventy-two Domains, Tang Rao had a friend named Yue Chong.
That guy was strange, he said he was looking for a woman, one he might never be able to catch in this lifetime.
Yet he kept searching, kept asking around.
Later, he found this woman, who still loved him, but did not choose to stay with Yue Chong.
The last time Tang Rao saw Yue Chong, he no longer went by the name Yue Chong, but what he was called was not important. What mattered were the words Yue Chong said to him.
He said: Since it's already the past, I will no longer be called Yue Chong, so the Yue Chong she loved can be considered dead. Some things are destined to vanish like smoke and dissipate like clouds.
After that, Tang Rao never saw this friend again.
