"Tofu-dreg project" (Chinese:豆腐渣工程) is a phrase used in theChinese-speaking world to describe a very poorly constructed building, sometimes called just "Tofu buildings". The phrase wascoined byZhu Rongji, the formerpremier of thePeople's Republic of China, on a 1998 visit toJiujiang City,Jiangxi Province to describe poorly builtlevees in theYangtze River.^[1] The phrase is notably used referring to buildings that collapsed in the2008 Sichuan earthquake disaster,^{[2][3][4][5][6][7]} and theBangkok Audit Office skyscraper collapse initiated by aftershocks from theMarch 2025 Myanmar earthquake over 1000km away, which was constructed with poor construction techniques and materials.^[8][9]

In China, the termtofu dregs (the pieces left over after making tofu) is widely used as ametaphor for shoddy work, hence the implication that a "tofu-dreg project" is a poorly executed project.^[8][9]

According to Chinese architectLi Hu, tofu-dreg projects in China are vastly outnumbered by buildings without construction flaws. Li said that in most cases, ill-constructed buildings do not collapse but merely have a reduced lifespan or leakages.^[10]

During the2008 Sichuan earthquake, many schoolhouses collapsed; resulting in the death of students. These buildings have been used to exemplify tofu-dreg projects. The collapses were linked toallegations of corruption in the construction of Chinese schools.

…School construction is the worst. First, there's not enough capital. Schools in poor areas have small budgets and, unlike schools in the cities, they can't collect huge fees, so they're pressed for money. With construction, add in exploitation by government officials, education officials, school managers, etc. and you can imagine what's left over for the actual building of schools. When earthquake prevention standards are raised, government departments, major businesses, etc. will all appraise and reinforce their buildings. But these schools with their 70s-era buildings, no one pays attention to them. Because of this, the older school buildings are suffer[ing] from inadequate protection while the new buildings have been shoddily constructed.

On May 15, 2008,Geoffrey York ofThe Globe and Mail reported that the shoddily constructed buildings are commonly called "tofu buildings" because builders cut corners by replacing steel rods with thin iron wires for concrete reinforcement; using inferior grade cement, if any at all; and using fewer bricks than they should. One local was quoted in the article as saying that "the supervising agencies did not check to see if it met the national standards."^[12]

The state-controlled media has largely ignored the tofu-dregs schoolhouses, under directives from the propaganda bureau's instructions. Parents, volunteers, and journalists who have questioned authorities have been intimidated or arrested.^{[13][14][15][16]} To quash the issue, riot police officers have broken up protests by parents, cordons have been set up around the schools in question, and reportage simply stopped.^[17]
