当我们每个人作为消费者进入商场购物时，对营业员来说，她（他）们每天应接不暇的不外乎三种人：即逛客、成交客和回头客。这里不妨对这三种用户作一全方位的分析。首先是迎客，他们大都不是来购买商品，而是在“逛”中了解所需乃至今后要买的商品之行情，比如唐量、价格、款? When each of us enters the mall as a consumer, for the salesperson, she/he is unable to accept more than three kinds of people each day: namely, visiting customers, closing customers, and returning customers. Here you can make a comprehensive analysis of these three users. The first is welcome guests. Most of them do not come to buy goods. Instead, they “see” to understand what they need to buy from now on, such as Tang, price, and money.
