thats a speculation.. show me where is it tested and inducted..??

Mach 2.5 Cruise missiles:
CJ-10 - In service, Used in 60th anniversary parade
YJ-12 - In service since 1999
HY-3 (C-301) - In service since late 80's
CJ-10:
YJ-12:
The 1st successful test of YJ-12 was completed in 1997, with all test flights over the ground for subsystems tests were completed in that year, and most of test flights over the water completed the next year. After a series of major upgrades, the missile received state certification in October, 1999, and entered Chinese service in very limited numbers for evaluation.
In January, 2004, series production of YJ-12 had begun, after a series of what Chinese claims of “major upgrades”. Chinese sources have claimed that the total number of YJ-12 in Chinese service is at least 816, which include all units from pre production series (pre-2000 era) and initial production (after 2004 era), but this has yet to be verified by official Chinese governmental sources or independent sources outside China.
Other Chinese supersonic missiles:
FL-2 (C-101) Mach 1.7-2.0
YJ-83 (C-803) Subsonic cruise, then accelerate to Mach 2 for attack.
There are also supersonic cruise missiles based on modified Russian designs but I haven't mentioned these because I'm only considering indigenous designs.
There are also a number of potent indigenous subsonic cruise missiles but the discussion is about supersonic.
