Wrong translation between Chinese Simplified and Chinese Traditional

[[e-mail]]

User story:
Users want to select the preferred Chinese translation from language settings.

Current behaviour:
Both is translated as 中文<-------Chinese

Expected behaviour:
Chinese Traditional as 中文（ZH-TW、正體中文、繁體中文）
Chinese Simplified as 中文（ZH-CN、簡體中文）

or just:
簡體中文、正體中文 So that users can differentiate these two.
