"More sunlight and fresh air are the main advantages of living in a rural area. Life in the countryside can provide an unforgettable experience. However, in rural areas, people may face challenges accessing high-quality education facilities. The best solution to this problem is to explore online learning options, which can serve as a viable alternative to inaccessible institutions."

Here's an alternative version with a lot of liberal rephrasing and simplification. Abundant sunshine and fresh air are the main attractions of living in the countryside. Country life can be blissful, but being close to nature also means you're farther away from good educational facilities. The best solution to this shortcoming may be online learning. (or "Fortunately, we have online learning to help remedy it.") * "living countryside" can work, but not "living rural/country area". This is because the suffix "-side" can sometimes function like an adverb too (e.g. stateside = in/to the United States). * I would try not to repeat similar phrases like "in the rural/country area" too many times.
