How do foreign-born people convert eight-character predictions?

Yesterday, a netizen asked me, should I convert my fortune telling for foreigners into Beijing time or local time? He said he was confused now. Some people say that the four-column prediction was invented by China people, and it is accurate to convert it into Beijing time. Some people say that the prediction based on local time is accurate, because they may be at night during the day. So I'm not sure. Both of them think it makes sense. I don't know who is right or wrong. I hope I can give him a reference. I think the four forecasts are good for foreigners, and it is difficult to solve practical problems with Beijing time or local time. Why do you say that? From the perspective of Yin-Yang and Five Elements, everything in the world is in the Five Elements, and so are China people and foreigners. The four-pillar prediction invented by sages is to express life through the four pillars of birth time with the concept of harmony between man and nature. We often say that people's fate is determined by eight characters, but this is not very appropriate. The eight characters are only the carrier of yin and yang and the five elements, and people's fate is determined by yin and yang and the five elements. Using eight characters to simulate life is just an approximation. Instead of absolute value, although people are born at the same time, because of their different places, their yin and yang and five elements of qi will be different, just like the sun, although everyone is bathed in sunshine, but because of different angles, there will be differences, so there is no way to express such differences in the four pillars. Our four-column prediction can only predict the normal state, and the abnormal things cannot be predicted. However, whether it is normal or abnormal, its yin, yang and five elements of qi are unchanged, but we just grasp it. The normal is easy to predict, and the abnormal is hard to find. Ancient sages did not study abnormal things. Four-column prediction is to express life by simulating yin-yang and five elements according to people's birth time. Is to use the four seasons of the five elements to discuss people's good and bad luck, such as Leng Xia fever in winter, vegetation sprouting in spring and stones flowing in autumn. It's true. It is very correct for sages to decide spring wood, summer fire, autumn gold and winter water, but it is not necessarily correct to use it in foreign countries. Maybe they are cold when we are in spring. They may be dark during the day. In some places, summer is always cool, and there are four seasons in a year. The sages have long said that "oranges were born in Jiangnan and grapefruit was born in Jiangbei". The oranges mentioned by the sages are actually not oranges, but the difference between people born in the south and those born in the north at the same time. China is still so, let alone foreigners. Many people like to study the Chinese characters of foreigners, and everything about Hitler and Reagan should be explored. The life of foreigners can be used as a pastime, but it is not suitable for research. It's like reading a martial arts novel. Although it's a palm technique, it doesn't exist in reality, and it's entertaining.
