This image depicts the interior of a classroom or lecture hall in Jiangjin, China. A male individual, seen from behind and wearing a grey hooded sweatshirt, is actively erasing a section of a large white board with a white rectangular eraser held in his right hand. The whiteboard displays various handwritten scientific or mathematical notations in blue and red markers, including "Direct shear," "C, φ," "Cq, φq," "Ceq, φcq," "Cs, φs," unit conversions such as "1 Pa = 1 N/m²," "1 kPa = 1000 Pa," and "1 MPa = 10⁶ Pa," along with a small table containing "F 1.0" and "T 0.47." Below the whiteboard, a light grey lectern or teaching station is positioned. On its surface, an open notebook, a red pen, a dark mobile device, and other small objects in a clear plastic bag are visible. A black gooseneck microphone extends diagonally upwards from the lectern. The lower part of the lectern features multiple horizontal ventilation slats and exhibits some faint adhesive residue on its top edge. The floor in the immediate foreground is light brown.
