Do these bagged GUDI pieces make up a single set?
So, I just Googled "GUDI" + "catalogue" and it brought me to the knockoff's parent company "Guangdong Xinlexin Education and Culture Co.,Ltd" or Xinlexin.com.

Xinlexin's GUDI product line has two subcategories that match the color scheme of these pieces.


Princess Alice line.
Modern Girls line.


Below are pictures from both lines that comprise of around 23 sets.  If you'll notice, each set has many unique identifiable pieces that just don't appear in the current six poly bags above. 

The only piece that comes close is that blue translucent piece in BAG 06, which sorta looks like the minidoll dress from Elena's Studio.



I don't think it's this dress, but regardless if it were, the poly bags are still short critical pieces to solidly decide on this set.  In fact, we're short critical pieces to decide on any of the other 23 sets.

Another point: We don't know how far back Xinlexin website goes when listing their knockoffs.  This could be a complete set before GUDI decided to list their wares digitally. 

Conclusion: We could safely say that these 6 poly bags are not from any of Xinlexin's current line of 23 sets, but due to lack of documentation, we can't say that these pieces do, or do not, form a complete set.
