"fitness"
This word has two pronunciations:
One is bitterness, which flows from mother to rhyme. What I read today is probably Ku à.
When I first read the ancient rhyme, I saw the mother's ending rhyme. Today's reading is probably [guò].
The word "Swift" means "Swift", which is often used in ancient names.
The ancient pronunciation of Zhou and Qin dynasties is pronounced as the entering tone word of the pre-stop sound on the tip of the tongue, which is generally pronounced as guat, and Wang Li's ancient Chinese onomatopoeia word is pronounced as the entering tone part of the moon.
So today, the words "scratch, scratch, scratch" are pronounced like this.
-reading a wide name is actually a relic of the ancient sound.
