On April 29th, according to foreign media reports, the Royal Melbourne Institute of Technology library suddenly sounded an alarm, and the school evacuated 600 people in the library. Firefighters initially thought that the reason was suspected toxic gas or gas leakage, and finally found that the "culprit" turned out to be durian.

According to media reports, some students in the university claimed to smell a suffocating and disgusting smell, thinking it was gas or gas leakage. This incident alarmed a large number of Australian police and firefighters to search at the scene, and finally found that the strange smell was durian that had rotted on its own.

A spokesman for the fire department said that they found rotten durian in the cupboard of the library, and believed that the smell of durian spread to every corner of the library with the air conditioning system.

The library of the Royal Melbourne Institute of Technology in Australia was closed for about three hours before it was reopened to students for free activities.
