7. Xiao Ya's average score in Chinese, Math, and English is 92 points (the full score for each subject is 100 points), and Math is 4 points higher than Chinese. Therefore, Xiao Ya's Chinese score is at least $\qquad$ points.
【Analysis】The total score for the three subjects is $92 \times 3=276$ (points). To make the Chinese score as low as possible, and given that Chinese is only 4 points less than Math, the English score should be as high as 100 points. 
This leaves Math and Chinese with $276-100=176$ (points). Therefore, Chinese is $(176-4) \div 2=86$ (points).
