When I went to the countryside to jump the queue, I didn't count the length of service when I retired, saying that there was no relevant information in the file. But I have never seen this document. What should I do? I just went through the formalities of going to the countryside last week. When I retired, the Social Security Bureau told me that there was no information in my file to prove going to the countryside. The Social Security Bureau usually gives priority to the copy of the case of moving out of the countryside with the official seal of the original city police station. Because only people with urban household registration go to the countryside, I went to the original police station to look for it four times, but there was no result (probably because the file was lost or damaged due to improper storage, and the police station refused to admit it). Later, I went to the Municipal Archives Bureau and found that I (and my parents' names) were on the list of educated youth. Later, I went to the village where I went to the countryside and found two players who knew me (both 70 s and 80 s). In the village, the two wrote the proof of the start and end time of my trip to the countryside, stamped the chapter of the village Committee, and then went to the town government to explain the situation and stamped the chapter of the town government. After I came back, I went to my parents' work unit and issued a certificate to prove that I was their child (because the police station could not find out that I moved from other cities to this city with my parents), and the most important thing was to prove my mother's urban hukou (because my child's hukou was settled with her before), plus my discharge certificate contained information about my going to the countryside in a county, a commune or a brigade before I served. This series of proof procedures can only be regarded as the recognition of my experience in the countryside by the Social Security Bureau. Remember, the most effective proof is the copy of the case of moving out of the countryside with the official seal issued by the police station in the original city area. Without this, we should consider the proof procedure of mutual confirmation in many aspects.
