Writing Balance Rule: The left radical (月) is narrow and compressed, while the right phonetic component (龙) is wider and must be balanced evenly to prevent the character from tipping over.
Simplification Logic: The traditional form 朧 simplifies the phonetic right side component 龓 into 龙, and keeps the moon radical 月 on the left.
Tone mark placement: Tone mark sits on "o" per main-vowel priority (a > e > o; in -iu/-ui the mark takes the second vowel).

2nd Tone (Mid-Rising)
Tone Pitch & Cadence: Tone 2 rises like a questioning English sentence (e.g., 'What?'), starting mid-range and shooting straight up to the top.
Sandhi: When followed by another Tone 2, the initial Tone 2 shifts to a high rising contour close to Tone 1, but underlyingly remains Tone 2.

Listening trap: Confusing the rising Tone 2 (lóng) with the flat Tone 1 (lōng) or dipping Tone 3 (lǒng). Pay attention to the upward slope.
