WHEN THE AQI IMPROVED ...

 Schools in the Manjung district were ordered to close on the 25th and 26th of June as the Air Quality Index level was more than 300 at one point on Tuesday.  Half way through the school day on the 26th, the lecturers and students were told to go home as the pollution level had gone to hazardous.
When I woke up on Wednesday morning, I got a call from Lai Yoong telling me that the AQI was around 100 that morning.  Wow!  What a difference!
So I decided to go back to the college to work on the key to the mural.  I had drawn the individual flowers and their common names.  For your information, it took me 3 hours to complete 9 flowers.
