Whether they are expensive or not is relative. In fact we don’t produce mediocre products because they don’t have a lower limit. If we produce according to mediocre standard, we can give you a lower price. However, the quality of after-sale service can’t be guaranteed. Of course there are a lot of customers who use our second-grade or third-grade products saying that these products are far better than what they are currently buying. Nevertheless, we will tell these customers directly that the price of these products doesn’t cover after-sale service. In fact all these products are within our sales range. Please tell me which kind of product you’d like to have.We are aiming at doing long-term business rather than a one-shot deal. In fact any enterprise needs profit to maintain the after-sale service. An enterprise without profit may disappear without a warning. And where are you going to find the after-sale service then?
