I'll have to go to Zuldazar because of this 20th anniversary event quest

Originally, you have to go to Boralus, talk to the Grand Admiral, and take a ship, but

Returning or new players can't go straight there because they haven't done the Battle for Azeroth war campaign.

In that case,

Go to Booty Bay below the Eastern Kingdoms -> Take a ship to the Barrens

Then go to 'Echo Isles' at the bottom of Durotar

If you take a ship there, you can go to Zandalar. (see image)

Please make sure to turn off War Mode because it is a hostile faction.

Before I found this out, I bought the Zandalari Wormhole for 8000 gold, but I can't use it because I have to learn Engineering.

In the end, I found out by reading the comments of the Wowhead Yankee bro ㅠㅜ
