If you want to be engaged in this industry and develop well in the future, then I suggest you go to the last training course, and recommend you to attend this training course: Beijing Rio Tinto Cai Ying Education and Training Center, a professional engineering training center, and the majors are: general layout, electricity, cost, construction, water supply and drainage, etc. At present, they are all one-on-one training, fully grasping the blind spots of students and tailoring the teaching materials! Online video will be online soon, so you can pay attention to the website: Design Journey!
