Hey, everyone, I am new here, are you all fine? I find some info are false, right? So, really waste some time, what do you think? And I find it seems there are a lot of design on the web, how many chances do you have to demo them? right, what do you think what your customers need? From my point of view, usually, most of them are middle class workers and they like to buy some stuff with good balance of cost and benefit. And really need to think of the right or proper point of selling the products. I remember the low price gold once is as low as just 80 RMB/g. And we need to think a little about the time of dropping suddenly from 6500＋ to around 3000.
