"男的性格強,占統治地位,生的就是男的"----is not true--in China, many daughters were born to be sent away by fathers --no matter what the mothers beg them not to do so, this is typical 男的性格強,占統治地位, still have daughters. There are too many examples..
And the others are worse about---- if the women are kind and mind, then they will have sons--this not only misunderstands the words of :“女子心氣平和,則樂有子。”but also suggest that whoever has daughers, she is not 心氣平和-
So i say all of these are "扯", not right, not true.
