Is this urn square or round?

The iron plate book says that for thousands of years, the urn should be round, and the square urn belongs to the word "prisoner" in China. The ancients said that the dead are uneasy and the descendants are poor, which means that the dead are not buried well, there is no peace, and the descendants are poor, so people who know the rules and the Book of Changes will not use the square. This is a rule left by our ancestors. I hope manufacturers and distributors will never mislead the next generation. If the ashes burned for thousands of degrees are put in marble urns, they will regain moisture and differentiate; Within five years, the ashes will be turned into mud and dust powder, and the deceased will rest in peace; Wood is not ideal; The five elements are impassable; Round ceramics are the best, but primitive clay is the best; If there is glaze inside, it will turn to the south like a tile to re-wet; Consumers are advised to use ceramic round urns, which are not glazed, but dragons and phoenixes and the best patterns are not used. It is also suggested that the urn should not be sealed with glue. According to the iron plate book, the cover should be sealed. There will be no males in the last three generations of sixty flowers. Remember, no matter what, there is Fiona Fang, so don't be jealous. The author is engaged in the Book of Changes, wishing peace and health! 2020.8
