What is this LHG thing i keep hearing about?

to get a run down on what this is basically you can abuse this to get any item in the game like "ANY ITEM" i kidding ya not
so to better what i'm trying to do in golden net in particular

to do this your self write a blank letter to any villager Drag it to slot 12 (the bottom right in the letter slot area) (asian releases only this doesn't exist on US/EU versions)
once the cursor loops twice right when it hits the text (showing on screen) the blinking line to show where you are typing from

here are the things i type it though things can be very similar and is easy to mess up. i try to use a visual and audio que to tell where i am since i'm way beyond where i'm intended to be.

i use this following information to get my setup for Golden Net Speedruns so the information i'm giving you isn't relevent for other runs at all (getting a golden axe doesn't break the rules as the speedrun is golden net not golden axe. so that's okay)
anyways here is the stuff i gotta put in properly otherwise i fail

and it goes in this order it should look like this when i'm done: https://cdn.discordapp.com/attachments/270746358430957568/653435270313672704/Screenshot_95.png

these are the things i type in below:
 Golden Axe
 モて
  Net
 ヨて
 Coconut
 ぁな
 Purple Rose Bag (unused)
 なな
 Golden Shovel Optional if you don't obtain a shovel in the shop
 ハて

if you don't wanna talk to joan this is something you can use
 Spoiled Turnips
 ぉな
