We obtained optical spectra (range 340-900 nm) of SN 2016jft,discovered by Giancarlo Cortini, on UT Dec.31.74 2016 with the 2.16 m telescope at Xinglong Observatory of NAOC and UT Jan.01.74 2017 with the Lijiang 2.4 m telescope of YNAO, respectively. The two specta are consistent with those of a type II supernova at its very young stage, showing a very blue continuum and a broad P-Cygni line profile of Ha. After correcting for a redshift of 0.0174 for its host galaxy UGC 05198, an expansion velocity of about 9900 km/s can be derived from the absorption minimum of Ha line.
