We obtained an optical spectrum (range 350-870 nm) of SN 2017dka,discovered by Jaroslaw Grzegorzek, on UT May 02.81 2017 with the 2.4 m telescope (LJT + YFOSC) at LiJiang Gaomeigu Observatory of Yunnan Observatories (YNAO). The spectrum is consistent with that of a young type II supernova, showing a blue continum and weak, broad Ha emission. The classification spectrum is also posted on the IAU Transient Name Sever: http://wis-tns.weizmann.ac.il/object/2017dka/
