Why am not able to get a grasp of PCB designing?

I managed to find a Design Recommendations for the chip in Chinese. The document gives me headache. Feels like I hit a roadblock again. I am attaching it with this reply.

Here is the translated version.

They have recommended to use a 4 layer board. Will it be possible to do it in a 2 layer board? I feel like it can't be done in a 2 layer board if I were to use the recommended trace width. Also, they recommend to use 8 mils or 10 mils as default trace width but if I use that, the traces won't connect to the ic pins.

Rerouter:
It can be done on 2, you just need to avoid crossings under switching nodes or the differential pairs, It makes it harder, but it is still possible. as for the trace widths, it is a recommendation, but you can neck-down the traces where they enter the IC if you wish

there reference layout looks very weird, they have there switching node taking up half of the PCB.

Working on the top layer, its quite possible to lay it all out, just a pain in terms of loop side, seeing as 8-27 need to be escaped

You mean all components on the top layer?
