Are there more stories in Chinese?

Penana is older than six months. There was a beta in April 2014. so it's surprising there aren't hundreds of stories in each category.

Are purple writing stories? Authors I follow have written multiple stories. There were 2000 stories in April 2015, and 2000 users in July 2015, 3000 users in September 2015.

Are authors furiously adding and removing stories?

There are many categories. About twenty.

Perhaps some categories are too new to have many stories yet.

In the supernatural category, most stories don't have tags.

 The way to add tags on mobile is obscure. You can only do it after creating the story? By going to Edit Story Info. I can't get tags to save in the app. Tags only became available in October 2016. Older stories won't have tags. Older members won't be familiar with tagging.
