Please teach me the usage of a kind of adjectives as attributive modifiers in Japanese. Thank you.

There are two kinds of mistakes in this sentence, one is the adjective modification error, but the tense error.

It should be changed to: yesterday, the same day, the same day, the same day, the same day.

You can't use よく to modify nouns, but ぃぃ. The く shape of an adjective is used to modify verbs and is an adverb.

よかった, よくなかった cannot directly modify nouns. If you want to express the past, just follow the noun with でした.

If you want to say no, it can be yesterday. Or: Yesterday, はぃぃはぁりませんでした. (Yesterday, はぃぃ𞊣𞇅.

Other adjectives are deformed in this way.
