"蹑磴" is pronounced as "Niè Dèng" in pinyin. Here’s how to pronounce it:
- "Niè" starts with an "n" sound, followed by the "iè" sound, which is similar to the "ye" in "yes" but with a fourth tone that starts high and falls sharply.
- "Dèng" begins with a "d" sound, followed by the "èng" sound, which is similar to the "ung" in "lung" but with a fourth tone that starts high and falls sharply.
When pronouncing "Niè Dèng" together, it should sound roughly like "nyeh deng," with attention to the specific tonal inflections of Mandarin Chinese.
