Standard Mandarin transliteration of "Mabel" — also seen as
梅宝 (Mei-bao) for Maybelle, Maple, etc. The most prominent fictional bearer in Chinese-subtitled media is Mabel Pines (
梅宝·
派恩斯) from Disney's 《
怪诞小镇》 (Gravity Falls).
梅 (méi, "plum") and
宝 (bǎo, "treasure") both happen to be common Chinese name characters, so the result reads as a natural-sounding name rather than obviously foreign.
