Is the red line method useful?

It is very useful to tie the red line. In ancient folk fairy tales and legends in China, there was a fairy who was in charge of the happy events of human marriage. People call him "the old man under the moon" and he is also known as the media god. According to the ancient book "Six Chapters of a Floating Life", "HongLing was held in one hand and a wedding book with a stick was hung in the other. The child was covered with a hair and galloped in the smoke." What I'm talking about is how Yue Lao draws a red line and builds a red bridge for all beings in the world according to the marriage documents. This answer is for reference only. Don't be blindly superstitious.
