The entrance hall of the firefly cave is made of logs and membranes, beside which stands wood carved red pillars engraved with gross profit totems. On the first floor, beside the staircase is a souvenir shop. It doesn't care about postcards, T-shirts, books and firefly dolls. It bought the popular MANUKAHONEY18+, a custom brand of Huaito Cave. The price is NT$80, which is cheaper than the supermarket, and hangs in another corner. If you like, you can take pictures and make postcards to make up for the regret that you can't take pictures in the cave. This can be charged about a dozen yuan. Up the stairs is a cafe and theatre. On one side of the wooden wall hangs photographs of the Maori patriarchal tower, Dinulao, and a British surveyor, Frank, exploring firefly holes many times. They are called the discovery of the Ninth Wonder of the world by later generations.
