@korean_yijun: You can cheat the Korean tissue test. 🧻 The tissue trick isn’t wrong — it’s just incomplete. It mainly shows airflow, but you can change the result just by speaking louder or softer. For 가, 까, and 카, air isn’t the only difference. Listen to the pitch and timing of the vowel too: 가 — low pitch + delayed vowel 까 — high pitch + immediate vowel 카 — high pitch + aspirated delay 💨 Same syllable shape. Different sound. What Korean sound do you struggle with the most?
