Shanglian East Pawnshop, West Pawnshop and East Pawnshop are all things. The bottom line is

"East pawnbroker, west pawnbroker, east pawnbroker takes care of things" is a bottom line, a picture is painted as a couplet, only the top line:

Nantong, North Tongzhou and North Tongzhou connect the north and the south.

PS。 The difference between up and down links:

Many people just grab a couplet or make a couplet, which is actually wrong.

The couplets are even and elegant. There is a basic law in couplets: the upper part is equal to the lower part. That is, the last word in the first half is going to be lost; The ending word of the next couplet should be flat and even.

The distinction between flat and parallel tones: The most convenient way to distinguish flat and parallel tones in modern times is to pronounce them at ordinary times. The first and second tones are flat, and the third and fourth tones are flat.

Therefore, "west" is the first sound, and the flat sound can only be the bottom line; "North" is the third sound and can only be the first part.
