As Liu puts it, her childhood coincided with a particular moment in China's modern history, when the closed world of Mao's China, with its revolutionary politics and intent to erase class hierarchies as well as various traditions, began to transform with increased connections with other parts of the world and global changes in political, economic, social, and technological systems. Her parents lived through the sweeping changes of Mao's regime and a country-wide famine. In contrast, Liu and her sister grew up in a rapidly urbanizing area and lived in more comfort than her cousins who were still in rural areas.
The memoir unfolds in a series of short vignettes from her childhood, from the day Liu learns about Chairman Mao's death to her creative plans to catch rats with her sister (for the country's goals of ridding areas of pests like rats, cockroaches, flies, and mosquitoes). In one vignette, she goes with her father to visit his mother (her grandmother) in the rural village where he grew up. She turns out to be a very mean-spirited old lady, and Liu spends the day outside with her cousins and other village children. She learns in that experience that people in China are still living in great poverty when the children are fascinated by her clean and well-made new coat on which her other grandmother had sewn a little white duck made of velvet.
The illustrations are quite beautiful, and Martínez has captured the look of a young girl's exuberance as well as some of the bleaker scenes about China's difficulties. This mix of the author's fairly pleasant memories about China and some historical details about more difficult moments like her father's hunger during the famine which drove him to eat leaves from that he could not identify is well done. (Some reviews I glanced at online by readers suggested that this mix, however, may make the graphic memoir not quite appropriate for young children, even though the publisher pitches it as a book for elementary school aged children.)
One thing I found interesting was that Liu's memories of China and her childhood are sometimes deceptively simple (or politics-free), but there is a lot of information woven into the stories about the state of China at the time. For instance, in the story about how she planned with her sister how to catch rats for the country (school teachers assigned children the task of bringing her two rats' tails as part of the pest eradication program), the fact that schools were essentially conscripting children into a program to control the pest program suggests other issues. The memoir gives a quick note about how the sparrow, for instance, used to be on the list of pests that children were to help kill, but then when people did kill off sparrows in large numbers, they ended up upsetting the ecological balance, and the insect population skyrocketed and became a big problem (helping to cause the famine earlier in the century).
It was also nice that the memoir did not end as many immigrant stories do with a triumphant arrival in the United States, with a kind of sense of salvation simply because she escaped a horrible past. In fact, she seems very much to cherish her childhood. For Liu, the choice not to end with her arrival in the United States may simply have been because she did not immigrate to the United States until she was an adult to work as a research scientist, and she wanted in this memoir to focus just on her childhood in China. However, she does end the memoir with a comment that her parents survived through much adversity in order to make a better life for her and her sister, and in much the same way, she hoped to create an even better life for her daughter.
