i want to know where should i go in guangzhou for buy cooton,chiffon and laces..?

Xiqiao Textile City in Foshan and Fumin Textile City in Humen, Dongguan are highly recommended for you.
For the first one, you can take Guangfo Subway line from Canton to Guicheng Station and then take a taxi to reach there.
For the latter one, you need to Dongguan from any bus station in Canton and then you can easily find bus to reach Humen in Dongguan City.
Hope the information can help you.
