"Electrical applicanes" inherits the phrase "no access to" to form "no access to electrical applicances".

Our village had no access to electricity, let alone use electrical appliances. Our village had no access to electricity, let alone electrical appliances.

Our village had no access to electricity, let alone use electrical appliances. Our village had no access to electricity, let alone electrical appliances.

Usually, our village had a few threshing grounds, which were flat and clean, making them nice places to sleep. Usually, our village had a few threshing grounds, which were flat and clean, making them nice places to sleep.

I've never heard of threshing before!

Usually, our village had a few threshing grounds, which were flat and clean, making them nice places to sleep. Usually, our village had a few threshing grounds which were flat and clean, making them nice places to sleep.

This comma is not needed because there is no reason to separate "which were flat and clean" from what comes before. I suppose you could keep it there if you like the way the sentence flows with it better. (Read it aloud with and without to decide).

When we went to the grounds, we carried awould carry pillows under our arms, a sheets in our hands, and a reeds mat on our heads. When we went to the grounds, we would carry pillows under our arms, sheets in our hands, and reeds mat on our heads.

Since there are more than one of you, there are also more than one pillow, sheet and reed mat. So, I think the plural may be more appropriate here. Maybe I'm being pedantic though...

When we went to the grounds, we carried a pillow under our arms, a sheet in our hands, and a reed mat on our heads. When we went to the grounds, we carried a pillow under our arms, a sheet in our hands, and a reed mat on our heads.

Although another reader suggested pluralizing the items you carried, I think that all those extra items burden the sentence. I think it reads well with the single items because it's implied that each person carried the three items, especially at the end "on our heads." Obviously, each of you has one head. You are describing the procedure that each person followed. A compromise would be "we each carried" or "each of us carried," but then "on our heads" might sound a bit strange, so you would have to decide between "their head" or "his/her head," all of which is not necessary because the original sentence works well imho.

We would spread the mat on the ground, lay down, and started chatting. We would spread the mat on the ground, lay down, and start chatting.

We would spread the mat on the ground, lay down, and started chatting. We would spread the mat on the ground, lay down, and start chatting.

We spread the mat on the ground, layie down, and started chatting. We spread the mat on the ground, lie down, and started chatting.

Even native speakers commonly mistake lie and lay. Especially in conversation. It's intransitive vs transitive. You lay something down. You lie down to go to sleep. But you will hear "Lay down and go to sleep" very often. Even though it's grammatically incorrect.

We spread theour mats on the ground, lay down, and started chatting. We spread our mats on the ground, lay down, and started chatting.

Now in this sentence, I think the plural is better because it reminds readers that each of you had a mat. "We spread the mat" could mean a group of people worked together to spread one mat, and using the plural clarifies that is not the case.

Older children would tell us stories they’d heard from adults—some from ancient Chinese myths, or tales about the stars right above us—while we listened to the soft chirping of summer insects.

We would wake up early the next morning, as it got lbright early in the fields and dew had wet our sheets. We would wake up early the next morning, as it got bright in the fields and dew had wet our sheets.

We would wake up early the next morning, as it got light early in the fields and dew had wet our sheets. We would wake up early the next morning, as it got light early in the fields and dew had wet our sheets.

I would revise to avoid the repetition of "early." For the first one, "before dawn," "before sunrise," or "before the sun rose" would work. Personally, I would reword the statement "dew had wet our sheets" because it reminds me of the phrase "to wet the bed," which is used when a person pees in their bed while sleeping. One option is "our sheets were damp with dew."

Honestly speaking, we couldn’t sleep well outside, but we kept doing it all summer. Honestly, we couldn’t sleep well outside, but we kept doing it all summer.

I nowwonder now if that was a form of primitive camping. Now I wonder if that was a form of primitive camping?. I wonder now if that was a form of primitive camping. Now I wonder if that was a form of primitive camping.

"I now wonder" sounds a little stiff and formal to me. You are not actually asking a question; you are making a statement.
