Hello Guozhejing, I think the first expression is not quite correct, it should be mould-breaker. A mould is a form in which something is made, if you break the mould you have to do something new. So here it says that Anderson, did something completely different from other writers. A 'bricks-and-mortar' shop is a real shop that you can go into, look at things and buy them. Bricks are the small blocks which buildings are made of and mortar is the 'glue' which sticks them together. The other type of shop which is becoming more common these days is an online shop. This does not have a physical building that you can walk around - you look at and purchase through the internet. Hope this helps Bob
