The three cardinal guides and the five permanent members are the etiquette of the Han Dynasty. Confucius never said that contemporary Confucianism does not allow people to copy these things. It is a kind of moral kidnapping for you to measure them by contemporary standards. What you have done is tantamount to putting the ethical content of China for thousands of years on the head of Confucianism, and then you take out something from a certain era. Everyone knows that it is out of date according to today's standards, and then say that this is Confucianism, and this is moral kidnapping. But in fact, as a contemporary Confucian, I won't copy them, and I won't use them to bind people around me, because courtesy is gain and loss. But who will manage the profit and loss of this ceremony is a question about righteousness and the profit and loss principle of the ceremony. What you do in the west is equivalent to doing so. You put all the ethical principles of the West for thousands of years, including the slavery era, including the Middle Ages, including the modern era, on their "Hill" tradition, and then you can tell them that your "Hill" tradition is dross and needs to be abandoned by enumerating some things that are simply unacceptable to contemporary westerners. But in fact, who in the west would agree? Let me start with two points: students respect teachers and children are filial to their parents. Confucianism does advocate filial piety and teachers' morality, but do you think that under the western education system introduced now, the relationship between teachers and students is still the one that Confucianism used to talk about? Is the parent-child relationship still the same as in the past? Moreover, teachers are elders, there is nothing wrong with respecting them, and there is no problem for children to be filial to their parents. You just take out some extreme cases and wait for others to agree with you, then you can disrespect anyone under the slogan of "equality"
