<p><strong>Updated：</strong></p>
<p>The new year is about to start again. The bricks that were not moved last year can be temporarily put away~
I hope you enjoy the present life and have a happy Spring Festival.
I'm happy to say that this update doesn't actually make any major changes, it's almost -
Updated the Spring Festival theme style;
And slightly optimized the recognition difficulty of the QR code generated when the device scan code is added;
And added the function of account cancellation (of course, I do not recommend you to use it);
Maybe also fixed some bugs by the way.
Alright, let's update it now! I also wish you a happy life~</p>
