Golden mushroom

I saw this golden mushroom growing thing at a shop in SSC selling all Taiwanese products! I remember seeing some 'friends' posting their pictures of the mushroom growing in FB but had no idea where they got them from! And WL bought a box for me to try!!!

The instruction was easy, just need to open up the square hole indicated on the box, cut a cross on the plastic bag, water the mushroom twice a day, morning and night and, wait for the mushroom to grow and cut to eat them!!

But, till today, I guess I had been waiting for about 10days or more, I see nothing growing out from the box... Sad!! And am wondering is it due to the insufficient sunlight? Or the watering of plant which I had clearly forgotten on some days and mostly watering it once a day!! Haha... And, to make me feel much worse, I saw some white ants growing out of the opening!!! Oh my... How can my mushroom grow??!! :(
