I found these Chinese MLP cards on Aliexpress & Taobao and my order finally came. Will be scanning and uploading them as I go.

This is card YH-F01-014. I suspect the “R” in the top right means “rare”, although this is silly as every pack has four of these “rare” cards guaranteed.

I am not a native Chinese speaker so these will be machine translated. If there are more accurate translations, I would be happy to edit the description.

甜心宝宝就像她的名字一样甜美可

Sweetheart Baby (Sweetie Belle) is just as sweet and lovely as her name. As a member of the Cutie Corps (Cutie Mark Crusaders), her biggest dream is not to earn a cutie mark but to become a talented pony who is praised and loved by everyone, just like her sister Rarity. She has a talent for singing but doesn't know it.
