Companies are stingy, not to mention the provident fund. It only pays 8% of its own 12%, and the running of Class 3 definitely kills you! A lot of odds and ends, the writing system is at sixes and sevens! It's boring every time I fill it out! No reward, only a fine! Want a promotion? It doesn't matter. It's hard! Private enterprises also have many related households! The bully's pit can't walk any further.
