Abstract: Quasicrystals are solid phases having long-range quasiperiodic translational order and non-crystallographic rotational symmetry. The discovery of quasicrystals has brought about a paradigm shift in the understanding of the structure of matters. The influences of it, which is in obedience to no previously thought-out plan, on the way of thinking of Human beings are enormous, profound and lasting. Daniel Shechtman won the Nobel Prize for Chemistry in 2011 for his discovery of quasicrystals. The past and the current status of quasicrystal research are shortly reviewed in this paper, in which the outstanding scientific contributions of Chinese scientists are introduced.
