How to change the correct language name

[Beck221]

In Class Crew, I can see there is a parameter named langague. And it's default value is 'en'. So if I want to change to support Chinese, what's the correct value for Chinese to define here?
language: str = Field( default="en", description="Language used for the crew, defaults to English.", )
I tried to change it to 'zh' but it failed with below error. Could someone help look into this issue?
crew = Crew( agents=[ city_selector_agent, local_expert_agent, travel_concierge_agent ], tasks=[identify_task, gather_task, plan_task], language='zh', verbose=True )
