What are the differences between “、” and “，”, and how are these symbols called?

The symbols "、" and "，" are both punctuation marks used in written Chinese, but they have different functions.

The symbol "、" is called "dun hao" (顿号) in Chinese and is used to separate items in a list or series. It is similar to the English comma but is used more frequently in Chinese. For example: 我喜欢吃苹果、香蕉和橙子 (I like to eat apples, bananas, and oranges).

The symbol "，" is called "dou hao" (逗号) in Chinese and is used to separate clauses or phrases within a sentence. It is similar to the English comma and is used to make the sentence clearer and easier to read. For example: 我喜欢吃水果，因为它们很健康 (I like to eat fruit because it is healthy).

In summary, "、" is used to separate items in a list or series, while "，" is used to separate clauses or phrases within a sentence.

In Mandarin Chinese, "、" is called "顿号" (dùn hào) and "，" is called "逗号" (dòu hào). The main difference between these two symbols is their usage: "、" is used to separate items in a list, while "，" is used to separate clauses or phrases in a sentence.

For example, in a list of three items, you would use "、" to separate them, like this: "西瓜、橙子、芒果" (xī guā, chéng zi, máng guǒ) meaning "watermelons, oranges, mangos".

On the other hand, "，" is used to separate clauses or phrases in a sentence, like this: "我喜欢吃水果，尤其是苹果" (wǒ xǐ huān chī shuǐ guǒ, yóu qí shì píng guǒ) meaning "I like to eat fruit, especially apples".

The symbol "、" is called a "ideographic comma", and is commonly used to separate items in a list. It is similar to the Western comma, but is smaller and placed at the baseline rather than the midline. The symbol "，" is called a "fullwidth comma" or "Chinese comma", and is used primarily to separate items in a list or clauses in a sentence. It is wider and taller than the ideographic comma.

The symbol "、" is called a "顿号" (dùn hào) in Chinese and is used to separate items in a list, especially when the items are short and do not require a full stop. For example: 我的爱好是游泳、跑步和健身。(My hobbies are swimming, running, and working out.)

On the other hand, "，" is called a "逗号" (dòu hào) and is used to separate clauses within a sentence. It is similar to the English comma and is used to indicate a pause in the sentence. For example 我很忙，所以没有时间看电视。(I'm very busy, so I don't have time to watch TV.)

① 、顿号 (dùnhào) : It is used to separate intems in a list.
Example: 我喜欢吃水果，如苹果、香蕉和橙子。(Wǒ xǐhuān chī shuǐguǒ, rú píngguǒ, xiāngjiāo hé chéngzi.) - I like to eat fruits, such as apples, bananas, and oranges.

② ，逗号 (dòuhào) - Comma: It is used to indicate a pause or break in a sentence, seperate different parts of a sentence, it's similar to a comma in English.
Example: 我喜欢吃水果，也喜欢吃肉。(Wǒ xǐhuān chī shuǐguǒ, yě xǐhuān chī ròu.)
