Tomb-Sweeping Day had better not visit relatives and friends, but visit other people's homes. In addition to a kind of respect for ancestors and each other, the ancients also believed that there would be a lot of yin after people went to the grave. Going to other people's homes will naturally bring Yin Qi home, which is extremely unlucky. Even if the other party doesn't say anything, he will feel uncomfortable in his heart! If you really want to get together, you can get together outside.
There is a saying in the countryside, "new shoes don't step on the graves of the elderly." It probably means, don't wear brand-new shoes when you go to the grave. Worship itself is a question of respecting the elderly and filial piety. Shoes are homophonic with evil. Wearing new shoes to worship their ancestors will bring them "evil" with bad meanings. Once the ancestors are angry, they will naturally not be blessed by him. How can there be good luck? So we generally don't buy shoes in Tomb-Sweeping Day, but wear new shoes.
It is very solemn for Tomb-Sweeping Day to pay homage to his ancestors. You can't wear red and purple clothes. It is disrespectful to your ancestors to go to the grave. Tomb-Sweeping Day usually chooses plain or slightly darker clothes, because it looks solemn and can express his grief for his ancestors. As a way to show politeness and respect for ancestors, we should also pay attention to the etiquette of clothes. That kind of bright clothes is extremely out of harmony with the atmosphere of sweeping graves.
