"put it into damp soil not really packing down soil just lightly put the bamboo into soil , keep it damn not soaked" This sounds like what I do.
I've not had any cuttings of any kinds of Dracaena plants fail, including large cuttings of lucky bamboo (D. braunii.) I do several of them per year and don't usually do anything with pieces smaller than 2 feet. I've always stuck those in pots of soil and when they have taken root, always send up a new stem from the roots. The water looks cloudy. Has something been added to it?
I think this is the 3rd discussion of yours on which I've commented. Starting to wonder if you're not seeing replies somehow?
