Is there a tacit understanding between the same zodiac and the same blood type?

The so-called zodiac, constellation and blood type, although there is no scientific explanation, do exist contingency. Even twins sometimes don't necessarily have a good understanding. However, it can be explained that if the zodiac, constellation and blood type are the same, it means that you two have similar personality characteristics, but the influence of the acquired environment will also lead to the imbalance of tacit understanding. Therefore, there is no need to pursue tacit understanding, just get along well. At the same time, two people's personalities are very close, and you will soon know each other's shortcomings, but this shortcoming is also your own.
