Cantonese is a Yue Chinese language spoken widely in Hong Kong, Macau and Guangdong, and its number system is one of the first topics learners study. Zero is pronounced ling, written with the character for a single drop, and appears in counting, years, room numbers and phone numbers where each digit is read individually. Short isolated recordings like this spread through language learning videos, flashcards and soundboards, where students and creators collect the full zero to ten set to practise tones and build simple counting sequences.
