It is also used in Korea[25] (Korean: 철밥통; Hanja: 鐵飯桶; RR: Cheolbaptong) as a name for officials, not only because of their job stability, but also because of stable income.[26] This phrase alludes to the jobs of civil servants being so stable that they would always be able to earn enough money to at least put food on the table. At the same time, civil servants must do their work to live just as rice is the staple of many Singaporean diets.
