Now merchants only advertise, preferring to spend a lot of money on advertising rather than serving consumers wholeheartedly like those who live by word of mouth. Most of them will fool, but if they can't, they will find various excuses to avoid procrastination, so that you can finally give up and achieve their goals. When this happens, everyone is unwilling, and this result is often the last thing our consumers want to see. But try to be calm when you meet them, and be patient when negotiating with them. It'll work out!
