This is a classic homophonic couplet. The first couplet says that two boats are swimming on the water, and the speed of rowing is not as fast as that of sails being blown by the wind.
In the second couplet, many pieces of music are played together, and the clear flute or rhythmic flute is more beautiful.
In fact, there is another mystery in the use of homophonic couplets.
"Ben" is the homonym of "Lu Su", who was the minister of Wu in the Three Kingdoms period. "Sail fast" is the homonym of "Fan Kuai", and Fan Kuai was the general of the Han Dynasty.
"Di Qing" is a homonym of "Di Qing", and Di Qing was a general in the Song Dynasty. "Xiao He" is homophonic for "Xiao He". Xiao He was a famous minister in Han Dynasty and one of three outstanding heroes of early han dynasty.
I have to say that this author is really talented and can come up with such interesting homophonic couplets.
Of course, the homophonic pun is a bit loose, and no convincing answer is given: "Lu Su is not as good as Fan Kuai, and Di Qing is not as good as Xiao He."
The second link: it is difficult to leave snow in Jiangnan; The north wind can't hold the height of the building.
In ancient times, two businessmen met in a hotel. A man surnamed Xue is from the north. The other person, surnamed Lou, is from the south.
After drinking for two days, I suddenly praised myself and boasted into a temper.
Lou's surname laughed at Xue's surname and said, "It is difficult to keep snow in the south of the Yangtze River."
The homonym of snow is that Xue, a northerner, can't eat in the south.
Not to be outdone, Xue had a brainwave and retorted: "The north wind doesn't live in the building."
Lou, if your surname Lou goes to the north, he can't settle down.
Couplets are evenly matched, humorous and witty, which embodies the ingenuity of homophonic techniques.
