Tell me as soon as possible how to write if I am familiar with the business.

If you are familiar with the business as soon as possible, you can write: Make clear the focus of your work and start with the main business study. Be diligent and try to master basic professional knowledge. Take the initiative to learn from colleagues with high work orders and strong business ability. Hard work, diligence, not afraid of hardship, is shameless. Because this writing and speaking will have a kind of self-motivation, giving people a kind of mentality that they are trying to get familiar with the business and trying to get familiar with the business.
