I am not sure how old I was at that time, I guess it might be five or six since I had not went to primary school until I was seven years old and I had used to live in my hometown with my grandparents. One day, when I was playing with my friends who were neighbors of my grandparents, an idea “I miss my parents, I want to go home” appeared in my mind. So I asked them “If you want to my home with me? there are so many kinds of delicious food you can eat.” They noded and were very happy to. But I found one problem that I had many cloths here and how could I took them home? After thought for a while, I decided to put on all of my cloths though it was summer. I can’t remember the how was the feeling of me but I believe it must be very hot since it took us at least one hour by walking from my hometown to my home in city. At the moment my mom opened the door, my grandpa also got behind us by bike, and again, I was captured currently.

I am not sure how old I was at that/the time, I guess I might/may have been five or six I didn’t go to  primary school until I was seven years old, so I lived in my hometown with my grandparents. One day, when while I was playing with my friends who were my grandparents’ neighbors, I suddenly thought “I miss my parents, I want to go home”.So, I asked them “Would you like to come to my home with me? There will be  so many different kinds of  delicious food for  you to eat.” They nodded and were very happy to follow/ come with me. But I had one problem: I had too many clothes there, how could I take them all home? After thinking for a while, I decided to put on all of my clothes, even though it was summer. I can’t remember how I felt, but I believe I must have been very hot since it took us at least one hour to walking from my hometown to my home in the city. At The moment my mom opened the door, my grandpa also arrived right behind us by bike, and once again, I was captured currently  taken back right away

at that time vs. at the time-both are correct BUT…
at that time -more for official usage, about a time in the historic past
E.g.: In Qing China women were not allowed to own property, which was usual at that time.

at the time-used about a particular occasion
E.g.: I didn’t have any money on me at the time.

an idea came into my mind/suddenly came to me/struck me/ I was struck by an idea/thought
