During the summer vacation, some college students come to construction sites to practice and experience the mechanical roar of the construction front line, feel the tension and busyness of the construction unit, and understand the real life of engineering workers. At 7:00 am on August 28th, Fu Chao, a junior majoring in Electrical and Intelligence at South China University, woke up early in the dormitory of the project department as usual and arrived at a familiar workstation before 8:00 pm. He turned on his computer and marked the positions of several reserved holes on the construction drawings. This was the 58th day of Fu Chao's summer internship. At 9 a.m., Fu Chao, who was interning at the Guangxi Smart Grid Project Department of China Construction Eighth Engineering Bureau, arrived at the construction site. He put on a safety helmet and fluorescent reflective vest, and under the guidance of his master, began this week's inspection work. This summer, the sunshine was extremely scorching, but there was a group of college students who did not choose to travel and relax or stay in air-conditioned rooms playing games and pursuing dramas. Instead, they came to the construction site to experience the mechanical roar of the construction line and feel the tense and busy work of the construction unit. It's a bit bitter, but it's worth it while you're young, "said Fu Chao. Every job has a hard side and feels the pressure transmitted by the job market. Lin Jingchun, a junior student at the School of Civil and Architectural Engineering at Guangxi University, and his classmates have decided to take advantage of this summer vacation the year before graduation to intern at a construction unit and accumulate experience for future job hunting. In early July, Lin Jingchun did not hesitate to sign up to participate in the summer social practice organized by the college for "Deep Engineering Frontline: Immersive Experience on Construction Sites". With a mindset of "based on reality and applying what he has learned", he came to the Huawei Guangxi Regional Headquarters Project Materials Department of China Construction Fifth Engineering Group for an internship. The high temperature was the first challenge he felt on the construction site. A few days ago, a batch of steel bars were transported to the site, and the master took me to inspect them. At that time, the outdoor temperature exceeded 35 degrees Celsius, and when I touched the steel bars through gloves, I felt hot. "Lin Jingchun said, as he saw heat waves constantly rising from the ground, the surging air blurring the scenery in front of him. However, the master did not retract his hand when inspecting the steel bars, as if he had become accustomed to it, This made him feel the dedication of the builders. The experiences on the construction site often have a direct impact on these college students who have been studying at the ivory tower. Lu Linhui, a student from Guangxi University who interned at the Materials Department, remembers that one day near noon, he followed his master up to the floor to inspect the steel bars. At that time, many workers were preparing to pour concrete on the floor, and he just stood by and felt a bit overwhelmed by the sun, but the workers were all buried in their own work, Beads of sweat kept dripping from their faces, no one complained, no one stood back. Upon seeing this scene, Lu Linhui took a photo with his phone and recorded it. During his lunch break, he saw that the workers' dormitory was covered in clothes that had been soaked in sweat during morning work. In order to relieve fatigue, workers usually drink an iced beverage at noon and then fall asleep to prepare for afternoon work. The knowledge of frontline work has also given this young man a clearer understanding of his chosen major. Lu Linhui recalled that when he applied for the civil engineering major in the college entrance examination, he considered it to be the best major he could choose in this school based on his exam scores. Now, he realizes that learning this
