The major fire in Hong Kong last night was heartbreaking, with the main source of ignition being bamboo scaffolding and protective nets, possibly caused by construction workers tossing cigarette butts.

In my impression, bamboo scaffolding can only be seen in rural areas during my childhood and now; the construction of high-rise buildings in the mainland has all switched to metal.

The use of bamboo in a bustling metropolis like Hong Kong is closely related to the obstruction from labor unions.
