These five auction halls are arranged in the long "factory", sandwiched between two aerial corridors. Visitors can overlook the trading process in the auction hall through the glass windows of the aerial corridor. Of the five auction halls, one is exclusively for seedling auctions while the other four are for various flowers. The halls are terraced. On the tall walls in front of the hall, there is a transaction clock controlled by a computer. The texts and data displayed on the clock represent various information, including the variety name and producer's name of the flowers on display, batch number, flower quality, unit, quantity per unit, seller code, specified minimum transaction volume, transaction volume, currency unit, bidding price, etc. The area around the big clock is divided into one hundred equal parts.
