To sum up, to be cheap, or underwear and stockings, these things are good in Zhejiang. If you want to wear something outside, it is Guangdong, which has good quality and is at the forefront of the trend.
There are many garment factories in Guangdong, but novices are hard to find. Generally speaking, they are in Guangzhou. It is suggested not to go to Baima Liu Hua area opposite the railway station, where roasted seeds and nuts are sold. You can choose a first-hand wholesaler, such as Zhanxi area, where the geography is not very good, so the price is lower.
The above suggestions are purely manual. If it helps you, please choose me. If you have other questions, you can ask them.
