What are the modal particles that change their taste when used? Like hehe

The list of modal particles that become obsolete when used is as follows:

First, haha. This word has the same effect as hehe. It used to refer to a person's smile, happy state, expressing his happy mood and showing a person's happy state. It also refers to people who are usually used for jokes. It is a kind of laughter of the speaker, indicating happiness, happiness, joy and excitement. Now it will be used to deny and laugh at someone or something. For example, what others say or attitude, you answer "haha", which means you don't know how to evaluate it. Anyway, it is not an attitude of approval, and it is no longer a performance of happiness.

Second, oh. "Oh, oh" used to be a common way to answer, and it also had a positive meaning. But now, if you see someone reply to you on WeChat or QQ, you will feel that this person is really perfunctory. I completely lost the meaning of affirmation before, but said I knew, knew, or was completely uninterested in this topic. Anyway, if someone gives me this word, I will end the conversation soon.

Third, so what? In the past, it was generally used at the end of a sentence to indicate the tone of reminding and exploring, or at the end of a declarative sentence to indicate the confirmation or emphasis of facts. Nowadays, in order to simplify their language, many people will directly use the word promise as an answer, indicating yes. For example, if someone tells you something and expresses his opinion, and you answer "what", you agree with his opinion very much.

Fourth, okay. In the past, "good" means "good" and is one of the common spoken languages, which is equivalent to "good", "good" and "oh". Compared with these words, there is a slightly hesitant meaning. But now this tone is generally with some dissatisfaction in it, and it is reluctantly accepted. Usually when people say this word, they will feel deeply helpless and don't know how to continue to communicate, so they will say "all right, all right" in a perfunctory way. The previous meaning was changed to the word "good this". "Fine" and "fine" sound similar, but they represent different moods.

With the gradual use of network language in life, many of our commonly used words have extended new meanings. For example, the word "wronged miss", our former physics teacher, used to call a lady or a very good girl, but now the word has been belittled. Moreover, modal particles have more meanings because they are used in more contexts, which should also enrich the language.
