As the eldest son of Zhang Zuolin, why is Zhang Xueliang nicknamed "Little Six"?

When I watched the TV series Jong, I found that Zhang Zuolin always called Zhang Xueliang "Little Sixth Son". At that time, Zhang Xueliang was ranked sixth at home. Later, I read some related knowledge and realized that it was not like that! So what's going on? Why is Zhang Zuolin's eldest son, Zhang Xueliang, nicknamed "Little Six"?

There is speculation on the Internet that Zhang Xueliang was born in June, and it is called "Little Six Children". This reasoning sounds reasonable, but it is unreasonable to study it carefully. Decades later, Guo Chunguang, the son of Guo Jingshan, Zhang Xueliang's confidant, revealed the truth.

It turns out that there is such a story. The name of Zhang Xueliang's milk is double happiness, which means double happiness. Zhang Xueliang's biological mother, Zhao Chungui, was Zhang Zuolin's original wife. Before Zhang Zuolin made his fortune, Zhao Chungui gave him a son, but unfortunately he died young. Later, Zhang Xueliang was born.

Zhang Zuolin saw that the newborn Zhang Xueliang was a handsome boy and liked it very much. Afraid of any more accidents, I want to find a fortune teller to calculate and avoid misfortune. At that time, Zhang Zuolin was already famous, and the fortune teller was afraid that it was not good, so he dumped a pot and asked him to find an abbot nearby.

after seeing the abbot, Zhang Zuolin explained his purpose. The abbot studied Zhang's father and son carefully for a moment, and then said to Zhang Zuolin, "Your son shouldn't be called Double Happiness. Tell you what, I'll cut you a paper man, write the word Double Happiness on it, and then burn the paper man, so that the Double Happiness will be gone, and your son won't encounter any disasters in the future, so you can rest assured to raise your son!"

When Zhang Zuolin heard the joy, the son finally saved it. Later, he thought about it and asked the abbot to give his son a nickname. The abbot said, "Don't look back when you take the child out of the door for a while. Go straight ahead. If you hear the first name called by others, you will take it as your son's name." Zhang Zuolin wrapped her son, picked him up and walked out of the door. Soon after she walked out of the door, she heard a woman shout, "Little Liuzi goes home for dinner.".

In this way, "Xiaoliuzi" became Zhang Xueliang's nickname and kept calling it down. Later, Zhang Xueliang once laughed at himself: "If someone called a bastard at that time, I would be called a bastard." Of course, Zhang Xueliang was not called a "bastard", and it seems that the name "Double Happiness" is no longer known, and "Little Six Sons" has always been well known.
