So once, when a policeman went to a food stall to order a bowl of roasted goose moustache, the boss deliberately said, "This adult knows how to eat. I don't know if you want a left moustache or a right moustache?" The policeman froze. "Is there a difference between a left moustache and a right moustache?" He asked. "yes. Of course there is! The left mustache is much better than the right mustache. " (Cantonese means that the left leg is much more delicious than the right leg)

So, from then on, it came out that eating roast goose legs, the left foot is more delicious than the right foot. Although today's police will no longer eat overlord rice, the mystery of the left leg still dominates the barbecue shop. Whether they sell ducks or geese, the left foot must be sold first.

It is also said that when a goose sleeps, it stands on one foot and uses its left foot.

So the left leg is tough and the right leg is soft.
