Specifically linked to the medical device industry, I personally think it's not bad. After all, China's population base is large, there are many medical units, coupled with the improvement of people's living standards, the demand for medium and high-end medical equipment products is also rising. So, in general, do medical equipment industry is still very promising ~ ~ but then specific to the medical equipment industry is to do sales or maintenance, if only from the economic point of view, I think sales than maintenance to be good. Because the medical device (especially for high-end medical device products) is high value-added, the profit margin is relatively large. So as long as you can make a certain sales performance, their income is also very objective! ~As for the maintenance of this piece of (medical equipment), on a personal understanding of the situation, as a result of the current practice of many of the domestic medical equipment manufacturers are sales / maintenance upgrade "integration" (that is to say, medical equipment manufacturers in the sale of products at the same time with the medical unit to enter into a contract, responsible for the latter in the use of the product a number of time for the return of the factory to maintain or Product upgrades, trade-ins, etc.), so the maintenance work is usually (fixed) in the production plant. And since this is the case, the income of the maintenance staff is more "limited" than that of the sales staff~~
