Standard bubble tea sugar levels in mainland China: 全糖 (100%), 七分 (70%), 五分 (50%), 三分 (30%), 微糖 (~10%), 无糖 (0%). Ordering culture treats this as a default required choice - many shops won't make a drink without you specifying.
usage
分 here means 'parts out of ten', so 五分 = 5/10 = 50%. The same fractional system applies to 冰 (ice): 正常冰 (normal), 少冰 (less ice), 去冰 (no ice).
