Yes, it is Clan. It is more troublesome to explain. Let me explain it briefly. And it has nothing to do with England, it is Scotland.
Tartan is the fabric of Scottish tartan, which is a general term for Scotland. Men wear Tartan skirts on formal occasions. Scotland is also divided into many clans. Each clan has its own patriarch and even laws. Every Scotsman has his own clan.
Each clan has its own clan. Representative marks, such as family emblems, etc., but the most important and obvious mark is that each clan has its own unique Tartan color and plaid, so that people can tell at a glance what clan the person wearing Tartan belongs to. Each family This special Tartan is Clan Tartan, which also represents the honor and unity of the various clans in Scotland.
The Tartan you buy on the street is generally not Clan Tartan. Clan Tartan is specially registered in the Royal Record House.
