The World of Noodoll is a range of characters featured on clothing, toys, stationery and children's books. Noodoll's clothes have been seen in Urban Outfitters, Tophsop, CULT Clothing and House of Fraser.

The current Noodoll toy, book, and accessories are also being stocked in shops and art galleries, including the Southbank Centre and the Tate Modern Museum in the UK. Noodoll products can also be seen in major retailers in Taiwan and Thailand.

Alongside Noodoll, YiYing's two 'Fashion Market' books triggered actual creative markets to spring up all over Taiwan and China. They have since become extremely popular and appeared in numerous publications such as Vogue and Elle Decor.
