Personally, it depends on who you are. If you want to enter a big company, you must gild yourself before you can learn more. You should pay attention to the standardization of health care products. To tell the truth, some big companies sell directly in China, but what they do in China is very irregular and not recommended. If you want to attract investment, I suggest not to do it as soon as you enter the business, but you did well when you were young, at least you should do it professionally first. Prescription drugs are similar to medical representatives, which can make money and exercise people, but the market is generally mature under great pressure and can be considered.
You can transfer, but it is unlikely if you work in the same company. If possible, I feel that the development of investment promotion will be greater, but your direction may change then.
Of course, what is said upstairs is right. These are all jobs based on personal ability. Best wishes.
