About 4000 bamboo poles are needed to build the framework of a 20 000 sq ft opera house,
which is considered small. More than 10 000 are needed to build a big, 100 000 sq ft one. Hundreds
of iron sheets are used for roofs and some walls. It usually takes 10 workers about a week to build
four small houses needed for the Yulan festival
