Problem on specific news url when change language

Hi,

My site has three languages, such as English, Traditional Chinese and Simplified Chinese.

I have a news detail page in english which has url like '/news/detail/2017/07/17/i-am-a-news-title'.

However, after a change the language, like Traditional Chinese (tc), using the bulit-in language selector, the url cannot point to correct news. The url will be '/tc/news/detail' only. 

What I want is the url would be '/tc/news/detail/2017/07/17/i-am-a-news-title'.

Please kindly tell me how to implement it.

Many thanks
