The helicity is important because it represents the basic topological configuration of the magnetic field the in solar atmosphere. The distribution of magnetic helicity in the solar atmosphere is presented by means of the observational (vector) magnetograms, etc. The comparison of observational helicities with magnetic ones in the solar atmosphere is also an important topic. The diagnostic of helicities provides an important chance for the confirmation on the generation of magnetic fields from the sub-atmosphere and also solar dynamo models. I would like to introduce some results of a recent study on helicity topics.

Future (ground and space) solar observational projects in China are also briefly introduced.
