This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
$ N& `9 O/ r7 h3 b/ p- l1. wash everything with broiling water, soak glutine rice overnight , using a bowl, cook inside microwave cooker ,( my rice cooker not easy to clean to oil-free stage), rice was properly cooked ( similar to sticky rice in dimsum restaurant ), left at table to cool down to same temp as back of hand, stir occaionly, sprinkle and mix 1 flat teaspoon of wine yearst ( white color, look like the fruit of lychi ), pour content into a jam jar , half full, put a piece of ceram wrap over jam, screw cap , put jar inside cupboard.
5 s h( w. W- b% h% e+ [- I* Z1 K2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.

in 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color
5 z# _) U1 }5 t5 h8 i4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)
