The difference between inner tank and outer tank

"Inner Can" and "Outer Can" are translations in Chinese dialects, which usually refer to "expert" and "layman". "Expert" refers to a person with professional knowledge and skills in a certain field, and "layman" refers to a person who lacks such knowledge and skills. In the workplace, "experts" usually refer to professionals with certain professional skills or experience, while "amateurs" refer to people who lack relevant knowledge and experience in this field.

For example, an accountant with professional knowledge and skills in accounting can be called an "expert", and a doctor who lacks knowledge and skills in accounting can be called a "layman". In the process of recruitment and career development, "experts" are usually regarded as more valuable talents because they can provide a higher level of work performance and value in specific fields.

It should be noted that "expert" and "layman" are not absolute concepts, and a person may have a certain degree of understanding and deficiency of a certain knowledge or skill.
