The official website of Jilin Provincial Secondary Construction Engineer Continuing Education Network is www.jljsw.com. 20 13, Jilin province launched the continuing education of second-level builders for the first time. They first register with the Provincial Building Association, and then they need to go to the designated place to buy the teaching materials designated by the Ministry of Construction before they can study. If they don't buy textbooks, they won't be allowed to study. The Ministry of Construction forced them to sell their broken books. The user name is JL00XXX certificate number, and the password is your ID number. If it is not correct, it may be that the ID number or ID number is wrong. It is necessary to contact the Provincial Building Association for revision, but it is necessary to bring the second-class constructor certificate to the Building Association of Room 270/KLOC-0 of Changchun Construction Building for revision. They need to review it.
