200 episodes. In the 20th episode of Detective Conan, Richard Moore and his wife Yingli attended the wedding of college students, and the restaurant was murdered. They blocked the knife with their bare hands and were accidentally involved in a series of murders. The wedding, one of the five rituals in life, is a traditional ceremony, which is equivalent to the legal notarization ceremony of modern weddings. Its significance lies in gaining social recognition and blessing, helping newlyweds adapt to new social roles and requirements, and preparing to assume social responsibilities.
