This proverb criticizes hypocritical people who hide their true intentions under the guise of personal preferences. A person claims not to like something (overcooked rice) but, in reality, they are just boasting (by eating well-cooked rice). It’s a way to highlight the hypocrisy of people who seek to build a reputation while concealing their true actions. An equivalent proverb in English could be: ‘Actions speak louder than words.’
