There is no better place in the world to buy wholesale fabrics than Guangzhou. Why? Because it is home to the largest wholesale fabric market in the world: the Zhongda fabric market. The Zhongda market is not one market but an area of 30 different HUGE wholesale markets. There are suppliers for every kind of fabric here, everything from Acrylic fiber to Zorbeez, Aertex to Zephyr, Airdura to Zibeline. Basically, if it exists then you will find it here.
But the problem is not where to go, the problem is HOW to find what you are looking for!
