Heidi may be a stranger to many, but when you ask a Swiss about Heidi, they will laugh and reply to you Peter Heidi's story is like the Swiss enjoying the perfect, free pastoral life between mountains and rivers. With a smile, my grandfather was abandoned in the mountains and sold to a rich family in Germany. Finally, I returned to nature and returned to Switzerland. The story was simple but it was tearful. I couldn't help but go to Heidi's house to see Switzerland and the mountains in Heidi's eyes.
