The charm of the Buddha lies not only in its size but also in its architectural artistry. There are 1,021 buns in the Buddha's coiled hair. These have been skillfully embedded in the head. The skill is so wonderful that the 1,021 buns seem integral to the whole. Another architectural highlight is the drainage system. This system is made up of some hidden gutters and channels, scattered on the head and arms, behind the ears and in the clothes. This system, which helps displace rainwater and keep the inner part dry, plays an important part in the protection of the Buddha.
