What kind of kindness did the Jewish nation remember in Shanghai during World War II?

I once heard a joke, saying that if you are hungry on the streets of Israel and shout "I am from Shanghai" (please shout in Hebrew or English), chicken legs will fly everywhere and you will be killed. Happiness is drowning in the ocean of chicken legs, which will suffocate you to death.

It is said that the origin of this joke is that when Jews took refuge in Shanghai and were trapped by barbed wire and could not come out to buy food, kind-hearted Shanghainese people quietly stuffed chicken legs through the gaps in the barbed wire for them to eat. They remembered the deep friendship of Shanghainese people and they still cherished it even after returning to Israel.

Don’t say thank you for your kindness, but repay you with practical actions - a rain of drumsticks.
