the La (腊) in Xi La (Greece or Hellas) can mean wax but it also refers to method of food preservation in China called Waxing where meat is dried and cured to have a waxy exterior, this is commonly done in the winter and hence the 12th month in the Chinese Lunar calender (actually usually in January rather than December) is sometimes colloquially called the wax month

I hope that's real because it's fucking hilarious 🤣

These are literal translations of names mostly chosen for sounding at least a little like the country's name in its own language

Deutschland

Deutsch

De

{德|dé} (meaning moral or virtuous)

{德国|déguó}

I assume it's because it's like "de" or something i.e. Deutschland

Tbf that's a literal translation of Belarus. It means 'white Russia'.
