What can we make of the name 九儿? Two questions about the childhood name of the pivotal character in Mo Yan's Red Sorghum Clan:  

Her childhood name was 九儿.  Does this suggest she was one of (at least) nine children?  I do not recall any point of the novel talking about any siblings but I may well have forgotten something.  And of course the novel could imply they existed, and just not talk about them.

And should I suppose that Mo Yan intended to use the homophony with 
酒 (wine)?  Or does Mandarin just have so many homophones that I should not make anything of this one?  In the story she has no special relation to 高粱酒 when she is young, but it becomes central to her adult life.
Because she born on 9th Sep of Chinese traditional calendar, it's a Chinese traditional festival, which we call it "重九"(double nine).
