My son was born in Canada. Should the birthday be based on local time or Beijing time?

This is too difficult! However, according to my previous survey, most experts said that they would use the "Central Plains" time. . However, the Central Plains time and Beijing time at that time did not seem to be very consistent. A few experts thought that the geographical environment affected fertility, so they thought that local time was needed to meet the requirements of fortune telling.

Do you find it difficult?

Conclusion: I think the calculated life span is better, so I will use which time. What did you say?/Sorry?
