What is the credibility of Beijing Huayi Publishing House in recruiting part-time typists?

I use my toes to calculate on the board:

I am not a typist, and my typing speed is very average, 50 words/minute (60 words/minute is the passing line).

50 words/minute X 60 minutes =3000 words/hour

It only takes more than three hours a day to complete 1000 words. 580 yuan gets it, and his monthly income is 580 yuan * 30 = 17400 yuan.

I work harder every day and finish 20,000 words in 7 hours. 1 160 yuan. My monthly income is 1 160 yuan * 30 = 34,800 yuan. It's more than 10 of my monthly income from working hard for 8 hours every day and doing management work.

My toes came to the conclusion:

Simple typing, such a high salary, this recruiter is either a fool or a liar.
