iPhone Siri no longer recognize “take a screenshot “ verbally

After I changed iPhone language from English to Chinese, Siri no longer works verbally with “take a screenshot” but still accept text entry.

How to make Siri work verbally with English even though iPhone language is not English ? I prefer English b/c it’s easier to find support due to my habits.

Otherwise, I appreciate where to find Siri words to use for non English language.
