What do you need to prepare for Shantou's wedding customs?

I attended a girlfriend's wedding the other day. The wedding is the same month that her girlfriend and her boyfriend registered to get married. This day is an auspicious day chosen by the man's parents. The man is from Shantou, Guangdong, and his parents live in Shantou. My girlfriend thought the wedding would be held on the auspicious day of the zodiac, but I didn't know that the man's parents said that they would do it according to the custom of their hometown, and get engaged first and then get married. Girlfriend wants to get engaged just because both parents and relatives have dinner together. I just found out that the man's parents said they would choose a date and time. After calculating the date and time, the man's parents said that the engagement date had to be at three in the morning. My girlfriend learned that the engagement time was actually three o'clock in the morning, so she had to get engaged by phone. At three o'clock in the morning, the man's parents called the woman's parents and then called her future daughter-in-law. The man's parents also said that they wanted the woman's girlfriend, my future husband and my parents had a sleepless night. Everyone is waiting to call and answer the phone, for fear of missing their moment. This is the first time I have seen and heard such an engagement ceremony, a unique engagement ceremony. ? Because my girlfriend and her fiance shared an apartment in Guangzhou, the man's parents said that according to the custom of their hometown, the man was not allowed to see her five days before her wedding, so my girlfriend had to book two rooms in the hotel for her parents and herself to live temporarily, which was nothing. The man's parents also said that according to the custom of his hometown, the woman's parents could not attend their son's wedding. My girlfriend's parents came all the way from other places just to attend her daughter's wedding. My girlfriend talked with her fiance on the phone about the wedding to be held in Guangzhou. Is it possible not to pay attention to these unwritten rules? She wants to get her parents' blessing at the wedding. This is her wish, but the man's parents refused, saying that this custom has been passed down from generation to generation, which means that the woman can only return to her family on the third day in return. Moreover, on the wedding day, the man's uncles and aunts. My girlfriend is very sad, but what can she do? At the wedding, my girlfriend was all smiles, but when I went to the bathroom with her, she cried. Yes, considering that parents are close at hand, they can't come to the wedding. Which woman is not sad? Men and women love each other and have good customs. Both parents should be grateful and bless each other. The world is big, and the two families have this dusty relationship. How lucky are you? Why should you stick to some details? Children are lifelong events, and men marry women. Which form is more grand than the sincere wishes of two families to each other? I also think that some customs in Shantou are awkward, but we should also consider doing as the Romans do. What are the advantages of different local customs? Some things are better to be open-minded. If you insist on your opinion too much, you may make both sides unhappy. Explain to your family.
