  We demonstrate that a Weyl point, widely examined in 3D Weyl semimetals and
superfluids, can develop a pair of non-degenerate gapless spheres. Such a
bouquet of two spheres is characterized by three distinct topological
invariants of manifolds with full energy gaps, i.e., the Chern number of a 0D
point inside one developed sphere, the winding number of a 1D loop around the
original Weyl point, and the Chern number of a 2D surface enclosing the whole
bouquet. We show that such structured Weyl points can be realized in the
superfluid quasiparticle spectrum of a 3D degenerate Fermi gas subject to
spin-orbit couplings and Zeeman fields, which supports Fulde-Ferrell
superfluids as the ground state.
