Abstract 
In this paper, I present the recently established hyperunified field theory (HUFT)(1,2) for all basic forces and elementary particles within the framework of gravitational quantum field theory (GQFT)(3,4) in hyperspacetime. GQFT treats gravity as a gauge theory in the framework of quantum field theory to avoid the long term obstacle between general relativity and quantum mechanics. HUFT is built based on the guiding principle: the dimension of hyperspacetime correlates to intrinsic quantum numbers of basic building blocks of nature, and the action describing the laws of nature obeys the gauge invariance and coordinate independence, which is more fundamental than that proposed by Einstein for general relativity. The basic gravitational field is defined in biframehyperspacetime as a bicovariant vector field, it is a gaugetype hypergravifield rather than a metric field. HUFT is characterized by a bimaximal Poincare and hyperspin gauge symmetry PO(1, Dh  1) (sic) SP (1, Dh  1) with a global and local conformal scaling invariance in biframe hyperspacetime. The gravitational origin of gauge symmetry is revealed through the hypergravifield that plays an essential role as a Goldstonelike field, which enables us to demonstrate the gaugegravity and gravitygeometry correspondences and to corroborate the gravitational gaugegeometry duality with an emergent hidden general linear group symmetry GL(Dh, R). The Taiji Program in Space for the gravitational wave detection in China(57) is briefly outlined.
