  Upsilon (1S) decay to Xi_cc +anything is studied. It is shown that the
branching ratio can be as significant as that of Upsilon (1S) decay to J/Psi
+anything. The non-relativistic heavy quark effective theory framework is
employed for the calculation on the decay width. Measurements on the production
of Xi_cc and likely production characteristic of the partonic state with four
charm quarks at BELLE2 are suggested.
