How to pronounce [n]/[l] in Chinese Pinyin

How to pronounce [n]:

Make the tip of your tongue touch against the upper alveolar ridge and let the airflow come out from the nasal cavity accompanied by the release of the closure in the mouth and the vibration of the vocal cord. The sound of [n] is more like the “n” in the English word “nine”.

How to pronounce [l]:

Open your mouth slightly, make the tip of your tongue contact with the upper alveolar bridge soft, and then let the airflow come out from the sides of the tongue tip with the vibration of the vocal cord. The sound of [l] is similar to the “l” in the English word “like”.

The Similarity:

[n] [l] are both with the vibration of the vocal cord.

The Difference:

[n] is a nasal initial while [l] is a literal initial.
