What is the octagonal pavilion at the gate pier? Is it just the decoration in front of the door? Is it practical?

1. China traditional houses ~ supporting doorframes at the bottom of the gate+carving some lions and other shapes ~ pier! 2. octagonal pavilion/wenfeng pavilion ~ feng shui+the treasure of moire town house in the eyes of the people! 3. Decorate the facade+express wishes ~ long life/wealth/exorcism/happy marriage/prosperous family, etc! The octagonal pavilion can also be used for pedestrians to shelter from the wind and rain+enjoy the cool and other blessings! Good luck!
