达人: people proficient in a certain field

In Chinese, "达人 (dá rén)" refers to a group of people who are professional and outstanding in a certain field or those who are proficient in a certain aspect.

"达人"，中文里是指在某一领域非常专业，出类拔萃的人物，也指在某方面很精通的人。

There is an argument that "达人 (dá rén)" originates from a Japanese word "たつじん", which means a master or expert who is proficient in knowledge or skills.

一种说法是"达人"一词应该来自日语中的"たつじん"一词，意思是高手，能手，在学问，技艺等方面精通的人。

Another argument is that "达人 (dá rén)" is derived from the word "talent" in English, referring to talented people. In terms of pronunciation, "ta" in "talent" sounds similar to "达 (dá)" in Chinese, and "len" pronounces similar to "人 (rén)".

另有一种说法，"达人"一词源自英文"talent"，引申即"有才能的人"、"高人"等意。且从发音来看，ta可音译"达"，len可音译"人"。

In China, you might often hear of the phrases like "旅游达人 (lǚ yóu dá rén)", expert in travel, "恋爱达人 (liàn ài dá rén)" expert in love, "数字达人 (shù zì dá rén)" math wiz, or "英语达人 (yīng yǔ dá rén)" expert in English. These phrases indicate that someone is very good at something. In Chinese, a person who has accumulated rich experience and achieved some success in a certain field after a long time can be called a "达人 (dá rén)".

在中国你会经常听到"旅游达人、恋爱达人、数字达人、英语达人"……之类的，这些"达人"就是指对某方面很厉害的意思。在中文字典里，"达人"是指经过长年的锻炼，积累了丰富的经验，而得到某个领域心得的人。

For example, "旅游达人 (lǚ yóu dá rén)" is someone who has rich experience in traveling; "英语达人 (yīng yǔ dá rén)" refers to a person who can speak English fluently and "音乐达人 (yīn yuè dá rén)" is the outstanding person in music knowledge or performance.

例如，"旅游达人"就是有丰富的旅行经验的人，"英语达人"就是能说一口流利英文的人，"音乐达人"就是在音乐方面非常_杰出的人等等。

In fact, "达人" is another modern and fashionable saying of "专家" (zhuān jiā) in Chinese. If you are good at Chinese and speak Chinese fluently, you will probably be called a "中文达人 (zhōng wén dá rén)".

实际上，"达人"也就是和"专家"差不多，只是换了个听起来比较时髦的称呼罢了。要是你中文很棒，中文说得很流利的话，你也可以成为"中文达人"。
