When and where was this series officially broadcasted in Continental China ?

我们是通过Netflix和Apple tv观看，并且该作品有中文译名

Netflix and AppleTV aren't available in Continental Chinese. So, there are no official zh-CN title.

I invite you to read the rules here and especially the part about the Chinese titles.

命名规则我已查阅，但是目前TMDB内很多海外作品，无论是电影、TV剧集、动画、很多都是没有正式在中国大陆上映，但是都是开放了编辑权限，大部分都有中文翻译，这明明是一件正确的做法，为什么要锁定编辑呢？

They aren't locked because we aren't aware that they were not release there. The Netflix and AppleTV productions (and some others) are directly locked as we are aware that this is not available there.

If they were not officially released in Continental China, they should not have a zh-CN title and it should be removed.

• A zh-CN title need an official release in Continental China.
• A zh-HK title need an official release in Hong-Kong.
• A zh-SG title need an official release in Singapor
• A zh-TW title need an official release in Taiwan
