Although the urine bubble is too big to be weighed, it is too small to be weighed. Is it ancient Chinese?

Although the urine bubble is too big to be weighed, it is too small to be weighed. According to relevant data, "The urine bubble is too big to be called, but its weight is too small" comes from the poem Knocking on the Door by Zhou Zizhi, a poet in the Song Dynasty, which satirizes the arbitrariness of officials at that time, meaning that although they have no power in their hands, they can still use small bodies to oppress the people again.
