Teacher Sets Lab Gear on Seminar Table in Shenzhen

Bright midmorning light floods through high windows, illuminating a polished floor and a large seminar table cluttered with open notebooks and loose papers. A teacher stands behind the table, arranging clear safety goggles and circular petri dishes in neat rows. The cool season is evident in the heavy fabric of the teacher's sweater and the crisp edges of the paper stacks. Warm interior shadows pool in the corners of the room, against the sharp, white skylight hitting the desk surface. The shallow depth of field blurs the background books, keeping focus on the precise placement of the glassware. One reflection of the overhead window frame glints off the rim of a petri dish in the foreground.
