Welcome to TMO @Moo-Crumpus!
Very good to see new users around here

One Question @chenliangchen.
What is your preferred official narrative regarding the brand and company naming.

Is it
1) Youyota Tablet by Youyota company (as mentioned in this reddit and linked TJC)
2) Youyota Tablet by Livermorium Ltd. (Or is Livermorium Moto Mod only?)
3) Personal project of yours with new company name, youyota branded

While there are only two mentions in da whole intanetz it is still possible to set this straight and prevent having to fight windmills later.
