Small lidded asian dish

This is a small dish that has a strainer built into the ceramic bottom I'm not sure it's for but I'm guessing it's some sort of tea container. It stands about three and a quarter inches high and about 4 in across maybe a bit more. It is a beautiful pale celadon green the pictures don't do that Justice. Just curious about it I don't think it's old or anything I just think it's very pretty, and the condition is excellent. Any info would be greatly appreciated I saw one dish that was sort of like it but it was three-legged.
