What is a children's song that you can still sing now?

Do you remember how to sing the songs from your childhood? "Going up the mountain to fight the tiger" "One, two, three, four, five, going up the mountain to fight the tiger, the tiger is not at home, and I will hit the squirrel." Nowadays, we are advocating the protection of wild animals, can we still sing "fighting the tiger" and "fighting the squirrel"? We should teach children how to protect animals, otherwise they will have to watch documentaries about what tigers and squirrels look like.

"Little Swallow" "Little Swallow, wearing floral clothes, comes here every spring. I asked Swallow why you come? Swallow said, the spring here is the most beautiful. Little Swallow, let me tell you, this year it is more beautiful. Beautiful. We have built a big factory and installed new machines. We welcome you to live here for a long time. "If I were Xiao Yanzi, I would definitely tell the children not to tell me! Because the big factory was built, the little swallows no longer come! The spring here is no longer beautiful! Stop forcing Xiao Yanzi! This song may be suitable to be sung again in half a century. Maybe then the factories will be environmentally friendly and energy-saving factories. I hope that humans will no longer eat bird's nests!

"Two Tigers" "Two tigers, two tigers, running fast, running fast. One has no tail, one has no ears, so strange, so strange!" Why are they "one and the same" Only one has no ears and one has no tail”? Not only is this weird, it’s like a horror movie, right? What happened to these two tigers... There is no way to explain it. Anyway, that's how we sang it. There are even weirder versions.

One has no eyes and the other has no tail. It's really strange... Only one has no mouth, one has no head, it's really strange... In short, they are just two mutilated tigers...

Are you also very familiar with these children's songs?
