Yes, it is somewhat difficult, but it is still possible. The critical thing is that you need to convince the VO that you will return to China after this single visit. Although you have the immigration intent, the actual immigration happens about ten years later due to the priority date to be current. Also, you will apply for the immigration visa in China, not file I-485 in US, and that means you will return to China.
Read the following words (the highlight with red color) from the website of US Emassy in China:
http://beijing.usembassy-china.org.cn/niv_misreps.html
"Shouldn't I conceal the fact that I have applied to immigrant, and that I have a prior visa refusal?
The risks of fraud are serious. Applicants who provide incorrect information, conceal relevant facts, or misrepresent their cases may become permanently ineligible to enter the United States. All approved applications are checked against computer records to see if certain information on the application was truthfully presented. It is common in China for an applicant to have relatives in the United States or a petition to immigrate on file. These factors by themselves will not necessarily prevent approval of your application."

Note: "a petition to immigrate on file" means I-130 filing/pending/approval, I-140 filing/pending/approval, etc.
