My sentences need your help Thank you.

Hello, 

I am not sure whether the two sentences make sense in term of grammar and semantics.
Can you give me a hand with checking them
Thank you for your help.

1. Graduating from junior high school, I didn’t take more factors—personal interest, parent’s suggestion, and teachers’ advice—into account, and make a hasty decision to major in electronics at five- year technical school at which I learnt nothing on the grounds that electronics didn’t interest me.

2. I continued to make self-examination and explore what I want to learn in high education after making a serious mistake to enter the technical school.

3. After the Cultural Revolution, the Chinese government has been beginning to make a self-criticism in order for China to take concrete policies to improve all aspect of people’s life. 

Hi,

4. People endured/survived hardships, caused by World War Two, which led them,after making a series of self-criticisms, to understand the significance of world peace.

The challenge in the original sentence is to clarify which noun each clause or phrase qualifies.

Best wishes, Clive
