I’m sharing here the websites I use frequently; please let me know if there are any better ones that I’m not aware of, and recommend some to me. Thank you in advance :) General forums: http://bbs.hcbbs.com/Haichuan Chemical Forum – this is the top choice, essential indeed. In my opinion, our forum could use further improvement in terms of organic and polymer-related topics； http://bbs.wcoat.com/index.php – The Wanke Chemicals Forum is also a good option; I used to promote there the idea of members earning points on their own. I’m not sure if it’s still available these days :lol ； http://bbs.chemdown.cn/index.php Chemical Materials Forum – There isn’t a large amount of material available, but it’s organized in a logical way. No payment is required to download anything; just create an account ； http://emuch.net/bbs/Xiaomuchong Forum – It contains a lot of content related to organic and refined topics, serving as a complement to Haichuan ； http://www.hgbbs.net/bbs/index.php Chemical Engineering Technology Forum focuses more on chemical processing technologies ； Professional forums: http://bbs.radcn.com/index.aspx – Radiation curing forum. Coatings, adhesives, and inks of the photopolymerization type represent an emerging industry; those interested in this field should pay close attention to it ； http://www.rylt.cn/Emulsified Oil Technology Network – Those interested in methanol gasoline, ethanol gasoline, and water-containing fuels might want to pay more attention to this site ； http://www.sto.net.cn/bbs/RubberTechnologyNet – A professional forum that offers excellent resources on rubber production and processing, additives, and standards ； Websites: http://www.chemdown.cn/ – a website for downloading chemical-related materials. No registration is required; downloads can be done directly, which is very convenient ； http://www.qupan.com/QuPan is an online storage service that offers a wide range of resources; take some time to search there – you’re sure to find something useful ； http://www.docin.com/Docin.com – Its biggest advantage is that all materials can be read directly, but some downloads are subject to a fee ； Standard download: http://www.bzfxw.com/StandardSharingNet. In addition to various industry standards, a large number of industry-related books are also available for download ； http://www.bzjsw.com/ Standard Technology Network; http://www.gb99.cn/ National Standards Website. Patent downloads: http://www.soopat.com/ Patent Download Site. It is possible to download all domestic patents, but searching for foreign patents doesn’t seem to work very well ； http://www.google.com/patents – for searching for patents on homing pigeons. I do not express any opinions on this website, but it is indeed convenient for downloading foreign patents ； http://www.chemyq.com/index.htm The chemical engineering engine allows for the search of patents; it also provides translation of chemical terms and product lookup services ； Hotel transportation: http://www.12306.cn/mormhweb/China Railway Customer Service Center – where you can check ticket prices and the number of available tickets ； http://www.ctrip.com/CTrip – a very convenient site for searching for hotels and flight tickets ； Business: http://china.alibaba.com/ Alibaba – It’s essential for checking prices of raw materials and products ； http://www.amazon.cn/AmazonChina: When you need books or information on a certain topic, you can search on Amazon, find the exact book title, and then download it from various forums and websites ； I won’t even mention other platforms such as Wanfang, VIP, Chaoxing, and CNKI; although I have accounts on those platforms, it took a lot of effort to get them, and I wouldn’t exchange them for rice. Does anyone have any good websites they can share with us, so we can all improve together :handshake
