I know a thing or two about this industry. The sweaters on e-commerce are all delivered from JD.COM or Taobao Tmall, and 80% of them are from Puyuan Town, Jiaxing, Zhejiang, where sweaters account for more than 80% of the national market. In which market do you get sweaters from Hengyuanxiang or other famous brands on Taobao? The big market is across the road and the trademark is on this side of the road. If you want to mark Hengyuanxiang as 45, you need to mark Playboy as 25. Hengyuanxiang sells more than 300 sweaters close to 400, but can't get 200. Plus the price of the trademark, it is more expensive than others. If you see the same model, you feel the quality is good, and the price is only over 200. In fact, the basic quality of that kind of goods is the same as that of Hengyuanxiang's 400. If you want to buy affordable, it is worthwhile to choose a brand that is not necessarily well-known. Even if the playboy brand is destroyed, basically all the goods on the market are thirty or forty, and there will be no real wool. If you look around, you will know that there are very few playboy sweaters over 200 on Taobao. If you want to buy a really thin sweater, you should choose at least about 200. If the thick sweater is about 300 in winter, it is definitely not real wool below this price. Also, the best way to distinguish wool is to find a thread and light it with a lighter after buying the reverse side. Real wool smells like roast chicken hair, and then a pinch of fingers will turn into powder when burned. If it is yarn and chemical fiber, it will become a knot in one's heart after burning. Rubbing by hand will not powder, for reference only.
