Song Wu bid farewell to Songjiang Houdao Hotel. What does the flag in front of the hotel say?

After bidding farewell to Song Jiang and Chai Jin, he went home to find his brother and went to a hotel in Jingyanggang. Three bowls were hung in front of the hotel, but Song Wu hired a bartender to serve wine. Song Wu drank three bowls in a row, shouted for good wine, and asked the bartender to serve wine. The bartender advised Song Wu not to drink three bowls of wine, but Song Wu was willing to listen and drank eighteen bowls in a row, instead of taking the bartender's advice and going with everyone. Climb to a flat place on the top of the mountain, get drunk and fall asleep on the stone. I heard the tiger roar in my sleep and broke my eyes. After seeing a tiger with an innocent forehead, I came to the park, surprised and woke up. I grabbed the whistle stick and hit the tiger, but I didn't expect to hit the trunk. The stick is broken. Song Wu threw away half a stick and fought the tiger with his bare hands. Later, Song Wu killed the tiger with extraordinary skills.
