Pinyin:
* Lún Dūn (伦敦) - This is the most common and direct translation.
* Lùn Dùn (倫敦) - This is a traditional Chinese character version, but it is less common nowadays.
Simplified Chinese:
* 伦敦 (Lún Dūn)
Traditional Chinese:
* 倫敦 (Lùn Dūn)
Pronunciation:
The pronunciation is roughly "loon dwoon" with the "oo" sound like the "oo" in "moon" and the "un" sound like the "un" in "sun".
Note: Chinese doesn't have a direct equivalent of the English "L" sound, so it's often pronounced with a slightly different "L" sound.
