Brother: The moon is out, it’s bright, Two wives and a man, come together to marry me, the three of them are the same as above A bed. Oh, fat lady, three of us are sharing the same bed!

Fat Woman: The moon is out and it’s so bright. How can three people sleep in the same bed with two women sandwiching you? I’m afraid you will meet the King of Hell with your life! Oh, my brother, I am afraid that you will meet the King of Hell with your life!

Little brother: You two, listen to me, don’t be afraid of the little fate meeting the King of Hell. Don’t think that my body is small, even though I am small, he is a lump of steel! Oops, fat lady, even though she is small, she is a piece of steel!

Fat woman: This little brother, please don’t be arrogant. I’m not afraid that you are just a piece of steel. I am teasing my fat woman today and fixing the rosy scent for you. Oh, my brother, I fixed that rosy smell for you!

Brother: Listen to me, bitch, I am an expert in dealing with fat bitches. If you don’t believe me, let’s try it tonight and tell you fat bitch to get out of bed! Oh, fat bitch, I’m calling you fat bitch, get out of bed!

Fat woman: Don’t you think I’m fat? Even though I’m fat, I always play with it. Sleeping with your brother in my arms tonight is worth eating chewing gum. Oh my brother, it’s worth eating chewing gum!

Brother: This fat woman was born fat. Her butt is as big as a wine vat, and her waist is as big as three arms. She wobbles when she walks. Oh, fat lady, you are wobbling when you walk!

Fat woman: This little brother, you are an outsider. You really don’t understand and have no vision. If you mess with my fat woman, I guarantee you will sleep soundly every night! Oh, my brother, I guarantee you will sleep soundly every night!

Little brother: Don’t carry that gunpowder gun when fighting a war, don’t use that old stick when fighting tigers, for the sake of our good health in the future, don’t ask for a fat woman when we get married! Oh, fat lady, why don’t you marry a fat lady?

Fat woman: You are a dirty little brother. How can a tiger not have a stick? Ask me to be your fat wife and help you carry a gun on the battlefield. Oh, my brother, I will help you carry the gun on the battlefield!

Brother: This little girl is very skinny. She only weighs thirty-eight. She has no fat on her face. There is nothing you can do about marrying me. Oh, you little pervert, there is nothing you can do about marrying me!

Skinny woman: The guy opposite is handsome. He stares at me in a daze. He is only four feet two, and he looks like a beef cabbage. Oh, my brother, it’s just like a beef cabbage!

Brother: This woman is so thin that she only has skin to cover her bones. If she really marries me, she will have to suffer every night! Oh, you little pervert, you have to suffer every night!

Skinny woman: You don’t know how to address this little brother. He eats flies and sprays them randomly. Although any girl is born thin, thin women have tricks. Oh my brother, the thin woman has a trick!

Skinny woman: This little brother is really stupid. At such a young age, he is looking for flowers. Today, he teased me, my little sister, and made you stand on your back! Oops, my brother, I’ve given you a leg up!

Brother: You are so stupid, girl. It’s easiest to just play around with flowers. I’m not afraid of the two women. Let’s try it together. Oh, fat lady, come up and try it together!

Fat woman: Don’t be so arrogant with your big mouth and horse teeth. How dare you show off your power at this point? You can be both fat and skinny. I call you little brother and climb up the wall. Oops, my brother, calling you little brother is like climbing a wall!

Brother: One is fat and the other is thin. He can dance and he has rhythm. I can see the two of them. Let’s eat the twice-cooked pork tonight.

Oh my sister, let’s eat that twice-cooked pork tonight!

Fat woman: You are not very tall at all. You can twist your waist by showing your teeth and flexing your claws. If I ask you to do Tai Chi, rolling up your sleeves is enough! Oh, my brother, rolling up your sleeves is just a trick!

Little brother: The fat lady talks and makes me laugh. You are not much taller than me. I will fight him like a drunkard with you. If you don’t believe me, let’s fight tonight! Oh, you little pervert, if you don’t believe me, I’ll challenge you tonight!

Brother: Don’t be so mean-spirited as this little girl. If you want to bring about your downfall, use my hard skills and defeat her with three or two moves. Oh, you little pervert, you can defeat him with three moves or two!

Skinny Woman: You are not shy, little brother. What kind of hard skills do you have? You can’t reach the end of a move or a half, so just kowtow and admit defeat. Oh, my brother, just kowtow or admit defeat!

Little brother: Listen to me, thin sister, he is the worst at my kung fu. He will punch you in the butt. Little sister, just scream! Oh, you little pervert, just scream, little sister!

Fat woman: Brother opposite, you have a shameless face, and you still punch us and pretend to be a tyrant. If you tease the fat girl, I will get angry and slap you with the Bagua Lotus Palm! Oh, my brother, I’ll slap you with the Bagua Lotus Palm!

Brother: Listen to me, this fat woman, if you hit her with lotus palms like that, the funny little brother will go crazy and make you drink rice soup. Oh, fat lady, I’ll make you some rice soup!

Fat woman: The little brother opposite is not good enough. He just opens his mouth and lets out the fart. The fat girl is so funny that she will put it in the vegetable tank for you. Oh, my brother, put it in that vegetable vat for you!

Little brother: Fat lady, come here, fat lady, don’t be afraid of your vegetable vat. I have a twenty-shot shot and I will smash your vegetable vat with one shot. Oh, fat lady, I'll shoot you to pieces and destroy your vegetable vat!

Fat woman: Come on, tell me, I'm not afraid that you have those twenty guns, but it's a pity that you have a gun but you can't use it. Oops, my brother, I can’t use it for nothing!

Brother: Don’t talk nonsense, don’t talk nonsense, he will load the bullet at any time, and the gun is already pointed at you, specifically to deal with you, fat woman. Oh, fat lady, let me deal specifically with you, fat lady!

Skinny woman: Don’t be so arrogant, little brother, and don’t bully the fat woman. The two little girls came together and took away your twenty rings. Oh, my brother, I stole your twenty rings!

Brother: Since you said that, sister, you said that if you take away twenty rings, I’m not afraid of you bullying me. I still have an old stick! Oh, fat lady, I still have an old stick!

Skinny Woman: Where are you, little lover? Brother Xiaoqing, listen, my little sister is telling you, your stick is nothing, it’s just like a screw. Oh my brother, it’s just like that screw!

Little brother: Little fat girl, come on, little thin girl, listen to me, brother, never brag or fart, nine out of ten will fall in love! Oh, my sister, nine out of ten love me!

Fat woman: Don’t brag. Come on, don’t brag. He is not shy. He has been married to you for more than half a year. He is so shameful and embarrassing! Oh, my brother, you are so shameful and embarrassed!

Brother: What a shameful person, he has lost his face. Where can I go to make an appointment with my sister? It takes time to be tight and slow to attack, and a loving couple will last forever. Oh, fat girl, a loving couple will last forever!

Fat woman: When I got up this morning, I went out. Why did I feel pain all over my body? I thought about that, brother, you are a bad man! Oh my brother, you are a bad man!

Brother: Get up early in the morning and go to Huashan Mountain. If your energy is not weak, your body will not be dull. I will tell you the truth, ×××××××× (I didn’t hear what JB thing I was singing clearly)! Oh, fat lady, ××××××××!

Skinny woman: I got up early in the morning to go up the mountain. I kept complaining that my feet were sore. My feet were sore and I recognized him. He’s your little brother. You’re in poor health. Oh my brother, it’s your little brother who’s in poor health!

Brother: Don’t be silly about this girl. I’m practicing that skill. I’ve mastered Iron Head Kung Fu and can penetrate earth-based walls.

Oh, you little pervert, you can break through the earth-based wall!

Skinny Granny: It’s not easy. It’s not easy. The steel plate of the car is bent. Look at you, it’s not even close to the wheat straw. Oh, my brother, he can't even keep brushing off the wheat straw!
