斉 means 'equal'

The equals symbol lies at the heart of 斉, which factors into words about equality, symmetry, and proportion (e.g., "She has a well-proportioned figure."). The most important bit of 斉 vocabulary means "simultaneous." With this word you can say that an audience bursts into laughter together or that birds break into song at the same time. Meanwhile, a negative prefix turns a 斉 compound into a term for "asymmetry," one of the seven principles of wabi-sabi. Also find out when 斉 serves as a radical or component in other characters.
