Why do giant pandas only listen to Sichuan dialect?

This question is easy to say, but difficult to say.

I feel like cats and dogs cannot fully understand and communicate 100% between people. Various trainings in the environment can help them understand human language to the greatest extent, and pandas are very intelligent animals.

Giant pandas born in the United States and Japan soon understood Chinese and Sichuan dialect after returning to China, and adapted to the local Sichuan diet.

Pandas may look naive, but they are actually animals with good survivability, otherwise they would become living fossils. Modern pandas know that they must rely on humans to survive.

So the ferocious beast transformed into a cute beast, and relied on and adapted to humans to the greatest extent. Therefore, the giant pandas on the screen can understand and respond to Sichuan dialect.
