Is it better to be a wine salesman or a medical consumables salesman?

This should be judged according to your own situation. First consider your advantages in that industry. Your knowledge of this industry. The second is the market analysis you have done. In the local market, what you do has more advantages, and there are more opportunities in that industry. Finally, you have to look at your long-term plan. If you want to develop this industry for a long time, just stick to it. I wish you success!
