I chose this source as it tells me about their use of language in their daily life. During the Japanese Occupation, citizens had to learn the basic language of the Japanese, Nippon-Go (Nihon-Go). Students, although allowed to use Romaji (words spent phonetically), were still obliged to understand and use both prints and cursive forms of the language, as well as a few hundred Kanji (ideograms).
From this source, it is clear that there was a shortage of food, leaving many to starve. Even food rationing provided insufficient food for the families. Hence, they planted tapioca, sweet potato, corn and groundnut as supplement. As it was mentioned that they had a rich harvest with their tapioca, much of their daily life must had been spent looking after their crops. I also chose this source as I am able to infer that the food they had consumed to sustain themselves were simple, cheap but nutritious. Families had planted foods such as sweet potato, corn and groundnut as supplement. They spent most of their time to manually pull out the tubes out of the ground. Hence, even with the shortage of food, they were still able to survive by improvising in their daily life.
I can learn from the source that civilians had to demonstrate proper respect to the soldiers, through the act of bowing. If one fails to do so, they would be kicked or slapped by the soldiers. Hence, the people were very careful to remember to now to the Japanese soldiers, so that they would not have to suffer from the beatings of the Japanese.
