I think companies of all sizes need accounting human resources. Big companies should focus on universities. Small companies with training background have no human resources at all, so unless you are strong, you can study accounting and find a bigger enterprise. Generally, you can be a clerk or cashier. At least a very rich skill. Moreover, after accounting is highly developed, you can take the primary title and intermediate title, and you can still be competent until you are 50 or 60 years old.
I taught myself the accounting certificate for two months, but I have worked hard. If you want to relax, you can sign up for class.
There are many accounting training schools in Beijing, including Stone Yongxin and Chun Xue. The cost ranges from 500 to 1000, depending on how you learn.
There is a difference between repetition and practice. Please call yourself for details.
