The political review of joining the party without crime is very strict. According to the website of the Shanghai Public Security Bureau, the political materials for joining the party without criminal proof and the need to obtain my family members and major social relations are very strict and need to be submitted many times. To join the party for political examination, I and my immediate family members must bring a political examination letter, ID card, household registration book and proof of no criminal record to the community where the household registration (residence) is located.
