Can the last sentence of the couplet be adcd, and the lower sentence can be AABB?

Strictly no. If it has a particularly good meaning, it can also relax the formal restrictions and become a wide pair. In general, the uplink is ADCD, and the downlink is also ADCD.

No. Not only can the structure not be different, but strictly speaking, the parts of speech of each corresponding word cannot be different. For example, both human-like and back-to-back are ABCB structures, but the parts of speech in the same position are different, strictly speaking, they cannot be correct.

Take a look at this old couplet – it's so widespread that almost every family has it.

Heaven says good things.

Peace in the Nether.

This is the shrine of the Lord of the Stove that was pasted next to the kitchen stove in the old home

It means to go to the Jade Emperor to report to work, and to say more good things about this family. When I come back, I will continue to bless my family's food and drink.

Analyze its format, i.e., the battle:

Heaven says good things -- peaceful, peaceful

The Nether Realm is safe and secure -- it is peaceful

1. Vocal rhythm battle - except for the first word with small defects on the top and bottom, all of them meet the requirements of the battle (according to Hanyu Pinyin);

2 The meaning of the word is also appropriate

3 The part-of-speech category is also eligible.

You say adcd - I don't understand what it means.

It's better not to use a for the next link, the repetition is too obvious and uncoordinated.

In the couplet, the upper couplet ends with a voice, and the lower couplet ends with a flat voice, and it is best not to have the same word in the upper and lower couplets, and each word is required to be neat.

It should be said that in this case, the battle will not be neat, so try to ensure that the format of the upper and lower links is consistent.

The couplet pays attention to the neatness of the word to deal with the battle, so the upper and lower couplets must be consistent.

(1) Everyone is happy every year.

Every family is reunited.

2) Far and near the ridges are verdant.

Layers of mountains and mountains are reckless.

3) Emerald and red, everywhere warbler swallow swallow.

Year after year, twilight and twilight.

4) Ups and downs, years of cold, cold, summer and summer.

Hurry, year after year.

How do you distinguish between upper and lower couplets? Grandpa is here to teach you!

To put it simply, the number of words is the same, the parts of speech are similar or similar, the meaning of the words is related, and the upper and lower links correspond to the opposite and the beginning and the end of the word. Couplets are divided into work pairs and wide pairs. The work pair refers to the number of words.

The parts of speech to the flat are strictly corresponding couplets. The wide pair only requires the same number of words, and it is evenly closed. The requirements for the meaning of parts of speech are not very strict.

To add, it would be more convenient to have couplets with related meanings.

The number of words in the upper and lower couplets is equal, the sentence structure is the same, the upper and lower couplets are opposite, the upper and lower couplets are equal to each other (avoid the three consecutive tails), the lower couplets are flat, the upper and lower couplets are the same, the artistic conception is close, and so on.

The number of words is the same, the parts of speech are similar or similar, the meaning of the words is related, and the upper and lower parts of the flat are opposite and the beginning and the end of the word.
