If you have ever used a reflector scope, like a Newtonian, you know what I'm talking about. The china scope is said to be not of a Ritchey-Chretien design(as the link said) but I think the image field flattening could be managed by adding a 3rd mirror as the article said or even by using a curved image receptor...just my guess
Comparison of the diffraction that can be observed around a star when observed with Hubble or Xuntian (simulation). Xuntian's third mirror would make the stars appear as dots and not as crosses as can often be seen in Hubble images. © CAS
