Supersu, Xposed And Weekly Rom : Need Help

[YhenZ]

Hi !

I just received my Mi5s Plus
I'm a novice at roms, root, twrp, and all this kind of stuff.
So I followed tutorials to replace the rom initially installed on my phone by the xiaomi.eu weekly rom for Mi5s Plus (natrium), using fastboot, ADB, and TWRP.
I also used TWRP to root my phone, by installing SuperSU, because I want to use Xposed.

But I read that SuperSU, Xposed and its modules would be deleted with every update of the weekly rom :s
Is it still true ? And is there a way to solve or get around this problem ? Because I really want to use Xposed modules...

Thanks in advance !

PS : Sorry my english is not very good :s

You just have to add the zip files again in TWRP after flashing the ROM update.
