青海省海晏县的金银滩,曾经是我国第一个核武器研制基地(221厂)的所在地。我有幸在这个基地工作生活了500天。那是52年前的事。当时,我在铁道兵十师四十六团(代号8091部队)服役。1963年5月,我们这些新兵训练刚结束,就补充到正在221基地执行修建铁路专用线的8091部队三营。在那里,我亲眼目睹了我国第一颗原子弹的出厂,通过我们修的铁路专用线运往新疆罗布 Haiyin County, Qinghai Province, the Silver Beach, once China’s first nuclear weapons research base (221 plant) is located. I have the honor to work and live in this base for 500 days. That was 52 years ago. At that time, I was in service with forty-six regiments of the 10th Corps of Rail Corps (codename 8091 unit). In May 1963, just as we completed the training of these recruits, we added to the third battalion of 8091 troops that are carrying out the construction of a railway special line at Base 221. There, I witnessed the factory of the first atomic bomb in our country and shipped to Xinjiang Rob by our special railway line
