The national director trained me, and I know one, that is, fission education in Nanjing, which was well done in Zheng Hong Building. Last year, there were several applicants in our company. After several days of training, all of them passed at one time except one who failed a course. You can search "China Training Research Network" in Baidu, or you can directly call 025-879 179 1 to find Mr. Liu.
