K3–35 is a prominent young Planetary Nebula (PN), which is the brighter one of two PNe detected 6 GHz OH masers up to now. Considering the rareness of 6 GHz OH masers in PNe, we proposed a relative motion measurement for such kind of masers toward K3–35 with the European VLBI Network (EVN) in full polarization spectral line mode, to study the morphology and kinematics of the central core where the masers reside, and understand the role of the magnetic field in shaping its circumstellar envelope. Here we just present the preliminary results of the first epoch observations carried out on 16 June, 2014, which showing that the 6 GHz OH masers in PN K3–35 can be detected even at the milli-arcsecond scale.
