Judging from the discussion of a problem or phenomenon called "Big Four" in the industry, I personally think that there is not much difference between the four companies, and the internal flow of the four companies is very frequent. It is common to work in Deloitte today, Ernst & Young tomorrow, Puhua today and KPMG tomorrow. This mutual infiltration of culture and work habits, active and passive knowledge sharing, also reduced the differences between the four companies. Some minor differences are as follows:

1. As a leader in the industry (both internationally and domestically), Puhua should have the most advantages in terms of company size and customer resources.

2. Many things have happened in Deloitte in the past two years, especially in American listed companies in China. The owners of China Expressway and Southeast Rongtong are Deloitte's customers, and so was Kelon in previous years. It doesn't mean that other companies have no accidents. As an accounting firm similar to an insurance company, this is only a matter of probability, but Deloitte's reputation has indeed been affected in the past two years. However, as a global company, Deloitte has undoubtedly done the best in four aspects of China localization, and Deloitte's mainland partners are estimated to be the most among the four. ?

Ernst & Young a few years ago was very different from now. Although they all use the slogan of "people-oriented", personally, there is a big difference. As far as I know, Ernst & Young didn't aim to be the first in the industry before, but won customers by excellent service and gave employees a good work experience, which is a bit like a martial arts expert who does not dispute the title of Jianghu. However, in recent years, Ernst & Young's business style has become radical. It can keep down the price for market share and ignore the high turnover rate of employees in order to reduce costs. During the financial crisis, Ernst & Young's reputation was also the worst among the four. However, we have to admit that Ernst & Young's training is the best of the four, at least in the past. ?

4. Although KPMG can't be ahead of other companies in China market, it has several heavyweight customers in several important industries, which is different from that of Anyong and Deloitte. But because of this, it is also the most stringent dress code among the four families. ?
