cicular then oval red dish took place from ground

I'm trying to tell the truth that happened in the fall of 1988 when I saw a UFO together with my family and other fellow villagers.  
I just happen to find your webpage while I was searching messages on UFO.  I haven't found any places on the web Chinawide thatI could report it after many tries. I feel responsible as a human being to tell what I saw that evening.
 That evening we heard a sound of bombing when we were having dinner.  As it was very loud, we rushed out of the house.  
We were seeing a red, exactly circular dish-like object of about 50cm rising near the water tower from the ground with tan thick dust aound.  (When I saw it, it has been on the way up, not just started rising)  The rising is straight up. When it came up to about 500km in a few seconds, it suddenly took an abrupt turning of about 120 degrees, and it became an oval shape, and the dust couln't been seen.  Then extremely fastly, it rushed  out of our sight in couple of seconds.
