There is a bad saying in folklore that couplets and door gods stick together and the coming year may not be smooth. However, these are ancient legends, which have no scientific basis and cannot be fully believed. However, it's best not to stick the couplets with the door gods, which looks neither fish nor fowl nor beautiful.
If you are going to put couplets on the door, just put them on, and you don't need to put up another door god. When pasting couplets, some people often paste the upper and lower couplets in the wrong place. If you can't distinguish clearly, you can distinguish the last word from the last word. According to the rules, the last word of the first couplet must be an ending, and the second couplet is an ending.
According to the traditional pasting method, the upper part should be pasted on the right and the lower part on the left. If you follow the new pasting method, you can paste the upper part on the left and the lower part on the right. In fact, the key to the division between left and right depends on the customs of the region. In some areas, we must adhere to the traditional methods and not change them at will.
It is best to post couplets between 6 am and noon on 12 on New Year's Eve, and try not to post them in the afternoon. In addition, when posting new couplets, you should tear up the old ones first, which means breaking bad luck, that is, removing the old cloth and making new ones.
