  "abstract": "We provide the first compact examples of type-changing generalized Calabi--Yau manifolds using Fei's construction of non-Kähler Calabi--Yau manifolds on branched covers of twistor spaces \\cite{Fei16}. The structure, which is generically of type 1 and changes to type 3, is constructed on the product of a hyperelliptic surface of genus three and a four-torus, $Σ_3 \\times \\mathbb{T}^4$, with starting point a non-Kähler Calabi--Yau structure.",
