Happiness at night

Tada!
This is 芒果啤酒(Mango beer) by Taiwan beer!
It looks so cute!
The taste is light like a juice.
I like it ♪

The snack is Katsu-sando(= a tonkatsu sandwich,Japanese style) from 勝王子(Prince Katsu) at Taipaei Railway Station.
It's good for beer.

It was so yummy ♪
However, why does Taiwan people like 王(= a king) or 王子(= a prince) so?
