I want to ask how to read Si Xiayan's Japanese, but I can't find the answer!

Analysis: This is not like Japanese vocabulary. If China's name is pronounced in Japanese,

The normal pronunciation will be: Yan = しかがん = Si Xia = Skagen.

Pronunciation: Si = し =し=si Xia Yangan

Pronunciation: Si = ぉもぃ = O Mo I Xia =なつ = Xia Yan =かぉ = Ka O.
