I may have misread or misinterpreted your post somewhat. But yes, I should have worded my own post better from the start, mentioning Hui rather than Muslim. And thanks for the map. I had thought Muslims had kind of disappeared in ten south, but it seems it may have just been they were too small a minority to see on other maps I found. I THINK Mao did something to Muslim groups down there in the past, but that might have been during general things against different ethnic groups in the south.
