Depending on your current situation, budget, and any restrictions or limitations you may be facing, here are my recommendations:
A .cn domain name that is just like your English name. For example, if your English domain is abcxyz.com use abcxyz.cn. The Chinese domain is not to impress Baidu. However, it shows a commitment saudi arabia number to providing Chinese users with an experience.
Host in China, which will require an ICP license. Although, this might even require you to have a business entity in China.
If you don’t want to mess with your current website, this is a good plan:
Keep all content on the same domain. Chinese-language content can be placed on a subdomain like zh.abcxyz.com, or (second best) Chinese-language content can be placed in a folder like abcxyz.com/zh. Baidu views the subdomain as part of the main domain.
Use a CDN to help make sure content loads quicker in China.
If there are resources that do not load in China, replace them, or completely remove them from the Chinese site.

4 – Use HTTPS
I know you’re almost definitely using it already, but I have to mention this because some people think Baidu can’t handle HTTPS. Actually, for several years already, Baidu has preferred HTTPS. If you don’t use it, Baidu will also show that as an error in Baidu Ziyuan.
5 – Use the Baidu “Ziyuan” tool to monitor for problems and submit webpages
Baidu Ziyuan is like Google’s Search Console. It’s a useful tool for finding problems on your website and submitting web pages to Baidu. But you will need a Chinese phone number to sign up.
Baidu Ziyuan can help detect the following:
Problems with robots.txt.
Number of pages indexed
Crawl rate/crawl errors
SEOers often use Baidu Ziyuan to submit pages manually to Baidu. Why do so? We often publish content, for example, a blog post, for new websites in multiple places— the website, WeChat, Zhihu, Sohu, and several other sites. This could result in duplicate content issues, so it’s best to submit to Baidu Ziyuan first, then publish off-site later.
We continue to do this for websites that might otherwise have problems with indexation. If your website is already indexed fine and you aren’t risking running into duplicate content issues, you can skip this step.
Baidu can submit new URLs via an API. Once you have a Baidu Ziyuan account, you have access to submit the URLs. Read a translated version of Baidu’s API support documentation here.
What if you don’t have a Chinese phone number?
Unfortunately, in that case, you can’t use Baidu Ziyuan.
