I don'twill give any synopsis hereno summary because everything in this article is unpredictable as same as, like my uncertain life. I will give no summary because everything in this article is unpredictable, like my uncertain life.

I don't undestand the register you want to use as you bounce between a rather sophisticated one and a simpler one. "Synopsis" is quite formal and I've barely even heard of it. A more natural costruction could be "... because I want everything in this article to be unpredictable..."

I dwon't give any synopsis here because everything in this article is unpredictable asin the same way as my uncertain life is. I won't give any synopsis here because everything in this article is unpredictable in the same way as my life is.

I dwon't give any synopsis here because everything in this article is as unpredictable as same as my uncertainmy eventful life. I won't give any synopsis here because everything in this article is as unpredictable as my eventful life.

You have not began telling your story from the time point of this sentence, so use future tense: you will (or will not) give a synopsis To structure 'as': "as (adjective) as (noun you're comparing with)" "Uncertain life" implies you feel doubtful about your life choices. If a lot of unpredictable things happen in your life, you can say "eventful life"

I dwon't give any synopsis here because everything in this article is as unpredictable as same as my uncertain life. I won't give a synopsis here because everything in this article is as unpredictable as my uncertain life.

I took a small bag and went to SZ. I took a small bag and went to SZ.

"I went to SZ carrying only a small bag" may be better

At thate time, anyone who wanted to go into SZthe downtown would have preparedhad to have a special pass card which was approved by the local government. At the time, anyone who wanted to go to the downtown had to have a special pass card approved by the local government.

"had to" indicates that that there was an obligation, and therefore the pass card was not only the best practice

At that time, anyone who wanted to go intoenter SZ downtown would have prepared a special pass card which was approved by the local government. At that time, anyone who wanted to enter SZ downtown would have prepared a special pass card which was approved by the local government.

'enter' is more natural than 'go into'

My two older sisters saw me off at the railway station, I forget my feelings thenI had no recollection of my feelings after my two older sisters had seen me off. I had no recollection of my feelings after my two older sisters had seen me off.

I feel this is more natural; if you want to keep your construction, "afterwards" would probably be better than "then"

My two older sisters saw me off at the railway station,. I forget myhave forgotten the feelings I had then. My two older sisters saw me off at the railway station. I have forgotten the feelings I had then.

My two older sisters saw me off at the railway station,. I forget my feelings then / forget how I felt then. My two older sisters saw me off at the railway station. I forget my feelings then / forget how I felt then.

My two older sisters saw me off at the railway station,. I forgeot myhow I feelingst back thean. My two older sisters saw me off at the railway station. I forgot how I felt back than.

You have already forgotten by the time you're speaking of this, so past tense "I forgot" "I forgot my feelings back then" would work, but it's a bit hard to understand (do you mean that at the moment, you decided to wipe your head clean of your feelings to start anew, or have you forgotten the emotions you felt back then?), so you can disambiguate it by saying "how I felt back then"

On the contraryother hand, I remembered how excited they were when they came to grseet me (at the same place) several months later, when I came back to see them from SZ, I was too moved I couldn't even to speak. On the other hand, I remembered how excited they were when they came to see me (at the same place) several months later, when I came back to see them from SZ, I was too moved I couldn't even speak.

On the contrary, I remembered how excited they were when they came to greet me at the same place several months later when I came back to see them from SZ,. I was too moved to even to speak. On the contrary, I remember how excited they were when they came to greet me at the same place several months later when I came back to see them from SZ. I was too moved to even speak.

This is a very sweet sentence.

On the contrary, I remembered how excited they were when they came to greet me at the same place several months later, when I came back from SZ to see them from SZ,. I was too moved even to speak. On the contrary, I remember how excited they were when they came to greet me at the same place several months later, when I came back from SZ to see them. I was too moved even to speak.

You are remembering it right now to recount it to us-- use present tense "I remember"

On the contrary, I remembered how excited they were when they came to greet me at the same place several months later when I came back to see them from SZ, I was too moved even to speak. On the contrary, I remember how excited they were when they came to greet me at the same place several months later when I came back to see them from SZ, I was too moved even to speak.

Nicely written.

What I have I experienced in such a changeunstable, unfamiliar, lively and energetic young city? What have I experienced in such a unstable, unfamiliar, lively and energetic young city?

What I have I experienced in such a changeable, unfamiliar, lively and energetic young city? What have I experienced in such a changeable, unfamiliar, lively and energetic young city?

Remember, the verb comes directly after a question word like what, where, who, when, and how.

What I have I experienced in such a changeablen ever-changing, unfamiliar, lively and energetic young city? What have I experienced in such an ever-changing, unfamiliar, lively and energetic young city?

When you structure a sentence, usually you swap the order of subject and verb. "What have I experienced?" "What did you see?" "changeable" is not a very common word, so if you want to say that SZ changes a lot, use "ever-changing" -- it is always changing

What I havehad I experienced in such a changeable, unfamiliar, lively and energetic young city? What had I experienced in such a changeable, unfamiliar, lively and energetic young city?

“What had I experienced” means “what had I experienced during my first several months in SZ, up to the moment described in the previous sentence. This is correct if the remainder of this post describes just those first several months.

My first destination was a toy factory ventured by Hongk Kong people. My first destination was a toy factory ventured by Hong Kong people.

I'm not that sure that "ventured" is the optimal expression, but it should be just fine

My first destination was a toy factory ventured byfinanced by people from Hongk Kong people. My first destination was a toy factory financed by people from Hong Kong.

My first destination was a toy factory ventured by(owned/ funded ?) by people from Hongk Kong people. My first destination was a toy factory (owned/ funded ?) by people from Hong Kong.

You wouldn't say "China people," so you should say"people from Hong Kong" "Venture" is a term in the field of business, but as a noun, not a verb.

My first destination was a toy factory, a ventured established and run by Hongkong people. My first destination was a toy factory, a venture established and run by Hongkong people.

My mother's friend recommendedsuggested that her daughter could host me. My mother's friend suggested that her daughter could host me.

My mother's friend recommended her daughter to host me. My mother's friend recommended her daughter to host me.

My mother's friend recommended that her daughter should host me. My mother's friend recommended that her daughter should host me.

When you connect "recommend" with a clause, use conjunction: "recommend that (action)"

My mother's friend recommended her daughter host me. My mother's friend recommended her daughter host me.

I assume that “host me” means you stayed (lived) at her home.

This structure is grammatically correct, but is a bit confusing to read and repeats "for" twice in close conjunction
