First of all, ask your water heater customers all have needs. You should try to get him to tell his needs, which are nothing more than water storage, safety, convenience, after-sales service, price and so on, and see what he cares about most. Secondly, we should know our own products very well and recommend the most suitable ones according to customers' needs. Some customers pursue cost performance, some pursue powerful functions, and some pursue fashionable appearance, which varies from person to person. Finally, from the customer's point of view, we should talk about the convenience and advantages of use, so that customers can have a very practical and yearning vision, and this single business will become. Remember not to let others feel that they are eager to sell products, but to introduce a comfortable lifestyle to others.
