Is it superstition that you can't visit relatives in July 15?

Not superstitious. Nothing is impossible. On July 15th, Taoism is called Zhongyuan Festival, Buddhism is called Yulan Festival, and folk custom is called Ghost Festival. Commonly known as July 30th. Mid-Autumn Festival is not only a religious festival of Taoism, but also a folk festival. On this day, Doumen held a routine ceremony to celebrate the birthday of local officials. At the same time, believers also funded fasting, prayed for the blessing of their ancestors, and asked local officials to forgive their sins and ascend to heaven as soon as possible. It is also the Buddhist Bonsai Festival. "Eye bug basin" is a Sanskrit transliteration, originally intended to solve the problem of upside down. It is said that the Buddha's apprentice had a healthy eye and was sent to the depths of hell because of his mother's evil deeds before her death. He asked the Buddha what the salvation method was, and the Buddha told him that fasting monks on the day of liberation of monks (July 15th, China) could save ghosts from the misery of hell. According to Buddhist rituals, meditation began in mid-April, that is, entering the temple to meditate, and not allowed to go out during the day. They end on July 15, which is called abstinence day, and they can come out to receive charity from believers. According to legend, from July 1st every year, the King of Yan ordered the gates of hell to be opened wide, so that the ghosts who suffered and were imprisoned in hell all the year round could get out of hell, get a short stroll and enjoy human blood. Therefore, people call July a ghost month, and this month is considered as an unlucky month, neither getting married nor moving.
