Gabriela has lived in Rio de Janeiro for the past 13 years and her grandmother is ill. He Juhua lives in Beijing, has the same age and her grandfather is not the least bit well either. The two girls did not know each other until Gabi decided to write a letter addressed to a Chinese teahouse, seeking help for her grandmother. He Juhua responds and the two girls start to exchange inspiring and interesting letters, quickly replacing them with emails that traveled a lot faster. Differences between Brazil and China, such as the allopathic and traditional Chinese medicine, dating in the 1950s and in current days, are some of the themes of their conversations. They were yet to discover a mysterious connection between them. The authors of this book – one being Brazilian and the other one Chinese – did not know each other when they created this delicate story.
