"Tofu-dreg project" (Chinese: 豆腐渣工程) is a phrase used in the Chinese-speaking world to describe a very poorly constructed building, sometimes called just "Tofu buildings". The phrase is notably used referring to buildings that collapsed in the 2008 Sichuan earthquake disaster,[1][2][3][4][5][6] and the Bangkok Audit Office skyscraper collapse initiated by aftershocks from the March 2025 Myanmar earthquake over 1000km away, which was constructed with poor construction techniques and materials
