It is wise to recruit people under 40.

Companies: Recruiters in factories, enterprises and institutions are generally recruited according to the age stipulated in the labor law. The elderly are not more than 45 years old (male). Female, under 40. Because a 45-year-old male employee will be 60 years old after working 15 years, that is, he can retire, while a female employee will be 55 years old after working for 40 years, that is, he will reach retirement age. Therefore, it makes sense that the maximum age of recruitment information is 45 and 40.
