school

, which was demolished to make way for a car

park

and an area for science block which was

also

a part of the

school

in 1980,

while

no change was seen in the layout of the playground in the southeast behind the

school

. Over the next 30 years, the car

park

was expanded towards the south and occupied the sports field.

As a result

school

building, which were adjacent to the main road in the northeast, remained unchanged during the period between 1980 and 2010.
