Hello Sheng, Vivian
In some cases, is not only enough to install the language pack, but also to configure the correct keyboard layout in order to obtain the right characters.
Please check the "Add keyboard" section at the next article: https://support.microsoft.com/en-us/windows/manage-the-input-and-display-language-settings-in-windows-12a10cb4-8626-9b77-0ccb-5013e0c7c7a2
