Failed to implement a different citekey generator based on language type via ternaries.

[YanMing-lxb]

goal:

if language if chinese:
    (auth(n=5,m=1).capitalize + '_' + year) 
else:
    (authAuthEa(sep='_' ).capitalize + '_' + year )

My code:
language(zh) ? (auth(n=5,m=1).capitalize + '_' + year) : (authAuthEa(sep='_' ).capitalize + '_' + year )
or
language.match(/^zh/) ? (auth(n=5,m=1).capitalize + '_' + year) : (authAuthEa(sep='_' ).capitalize + '_' + year )

Cannot correctly recognize zh tags or zh-CN tags from lauguage fields
