This morning, when I spent timeile I was on TikTok, I came across a famous old Chinese song.

Colloquially speaking we just say "I was on (this site)", but if you want something more formal, you can also say "I was browsing on (this site)"

This song is from an episode of the TV drama Journey to the West, and is namcalled “Young Girl’s Affection".

"This TV dramaJourney to the West was shot in 1986 and it was very popular at that time.

I think it's more natural to use the name after you've introduced it, but your original phrase was still correct.
Since you're already using past tense by saying "it was popular", the "at that time" is redudant and can be removed.

This song described the love between the kingQueen of thea kingdom of women and a Tang Monk.

Since the kingdom is of women and you later refer to her as "lady king", I assume she's a woman, and therefore we'd call he a Queen. If you want to stress that she's the Queen of the kingdom of her own right, as opposed to a Queen who was merely a woman who married a King, then you can clarify and call her the Queen Regnant.

I'm going to make any future modifications using this assumption.

The main idea of the story was that the kingQueen fell in love with the Tang Monk and the Tang Monk was also interested in the kingQueen.

The lady kingQueen wanted to get married to the Tang Monk and live a happily life for the rest of their lifeves, but the Tang Monk could not stay because he had to go to west heaven to get scriptures.

When the monk left the kingdom of womaen, the lady kingQueen was very reluctant, but she had no wayother choice.

So whatThe only thing she could do was only sing this song to see offthe Tang Monk off.

This song was very touchingimpactful and emotional and it touched many people.

You used 'touching' twice in one sentence so I wanted to reduce the repitition. Saying something is impactful is a common compliment and pairs well with emotional / touching stories.

But the song I heard on TikTok this morning was very special because it was in English vision: a. A beautiful female tiktoker translated it into English and sang it perfectly.
