It’s just because you may not need it yet, so you are disgusted with it. When you want to build your own brand and you have the need, wouldn’t it be good to communicate and learn from them? When I was a trademark agent, I used to proactively contact customers through some phone calls. Market competition resulted in the need to take the initiative. However, when it comes to customer selection, I really need to stand on the customer's side and make constant phone calls to harass them. It is indeed undesirable for customers not to understand their true intentions. I am also opposed to it. I wish you a prosperous business!
