Yesterday I used the adapter sent to me by my friend because it was not the same as what we usually used, so I didn’t know how to debug this adapter at first, but after that, when my friend taught me how to operate step by step, I still felt very simple. Friends say this adapter is new so it’s better than previous versions in terms of performance and usage, and I’ve just used it without a clear feeling that I’m sure my friend’s choice is correct. He often sends me something that he thinks is better for himself. Although we are far from seeing each other regularly, the feeling of mutual concern can be deeply felt. Sometimes I send him something special.
