Is there a bullet train between macau and yiwu? If yes, then what is the fair and timings?

No direct bullet train service is available between the two places. To travel by train, I suggest you go to Gongbei border to cross the border to Zhuhai. Then walk to Gongbei Bus Station to take a bus to Guangzhou Provincial Bus Station. Upon arrival, walk a few minutes to Guangzhou Railway Station to take a normal express train to Yiwu in 17h or longer. This way seems a little complicated.

Then here is another way: there are direct buses from the City of Dreams and Grand Emperor Hotel to Zhuhai Airport, where take a flight to Yiwu.
