We should not focus on whether you are expensive or not. Every industry should get a dignified income after paying for labor. We always feel that customers don't understand our value when we sell services; when we consume services, we feel that we should enjoy a low price, which has nothing to do with cost and is close to 0. For unlocking, we need to focus on whether we can guarantee safety, solve problems and improve efficiency. This is also a basic standard to consider a modern service practitioner. It's not a drought and flood industry. I'm starving, I'm opening, I'm changing, I'm closing. Compared with those who sell vegetables and goods, the industry is more uncertain. So if you think there are other people besides the lock company who are willing to help you solve the problem at a lower cost, choose other people. Most of the time, the company may be a cost-effective choice when you encounter the problem of unlocking.
