If I were the leader of Haier, I would first hate the supervision of product design technology and quality, as well as the handling of users' return requests. Products that are not qualified in design and production must never leave the factory, especially electric water heaters, which threaten the life safety of consumers. Moreover, products that consumers are dissatisfied with (including design and quality) must be returned instead of advertising all day. What they did in reality made consumers shudder. Haier is a big brand. If a product scares consumers, consumers of other products of the whole Haier brand (including their relatives and friends) may not buy all of Haier's products again, because no other brand products can replace Haier. On the contrary, there are more good products than Haier. It is precisely because there are many people who support domestic products in China that Haier has been advertising for a long time, and its early sales performance is good. However, if Haier does not control the quality of product design and production, it will gradually lose a large number of users and Haier will gradually decline. Therefore, in order to do a good job in Haier, we must first deal with the supervision of product technical quality and the handling of users' return requirements. If the quality of product design technology is good, users will not return goods. Once there is a problem with the technical quality of product design, consumers will ask for a return, and the seller must satisfy their wishes. Users who are dissatisfied with Haier's previous handling methods must find ways to recover and avoid geometric losses.

Let's write these first, hoping to help Haier and the landlord.
