When will our lockdown come to thean end?

I can still can remember back to 2019 I, when my community was locked down in my community because ofresponse to the pandemic's first surgwave.

I felt like I was in jail during that time.

Without "like" it's stronger, but I didn't feel that strength of expression was supported yet by the text.
Keeping it the way you wrote it originally is also valid in you want to be more emphatic, but in that case, I'd suggest you move the anecdote about forgetting your phone closer to the beginning of the essay so the reader understands why you're being so emphatic. Otherwise, it's unclear why you personally felt the suffering so acutely.

Now 2, two years lafter, a Covid variant once again swenteps across China.

In American English, we typically spell out numbers of smaller quantities.

EThe situation is especially dire in ShangHhai.

English doesn't know 上海 is two words.

Until nowTo this day, Shanghai is still under strictly lockdown orders.

I heard on the news from media that many people in Shanghai are suffereding from food shortages and medical insufficient medical resources.

TIn fact, the local medical resources are nearly run outexhausted.

I lived in a small city, not thea metropolis city like Shanghai, Bbut I am also struggling everyday.

For example, I have to scan two codes before I entered any doors,whatevermay pass any threshold, whether it be to a community door,center, a supermarket door,park door,etc.., or a park. Every door and every gate stands closed and guarded, and we, once free to roam, creep about under suspicious eyes in this new prison world.

While I appreciate the concrete imagery of a door, I don't think the text supports making doors (typically mundane) a poignant symbol of lockdown fears and limitations.

I think you could try if you added more text that emphasizes the feeling you want doors to convey, but that's beyond the scope of my editing right now.

I suggested something in that vein and tried to tie in your prison comment from earlier, but I didn't do an amazing job, and I think I overdramatized it hahaha.

It's awkward,because I can't be cannot even entered in my own home without scanning theose two codes.

I keep praying for the people of Shanghai people, Hhopeing they will getbe free soon.

We can't jusjust cannot afford toso much misery.
