Why is "Good Wife, Wise Mother" trending?

Wikipedia Overview

"Good Wife, Wise Mother" is a phrase representing a traditional ideal for womanhood in East Asia, including Japan, China and Korea. First appearing in Japan, the four-character phrase "Good Wife, Wise Mother" was coined by Nakamura Masanao in a speech on March 16, 1875. Even though the Meiji government was redefining the role of women to that of one only in the home, some women were still used for manual labor outside the home. "Good Wife, Wise Mother" accompanied the existing phrase "wealthy country and strong army" . The side by side usages of the phrases was reflected in the transformation of the Imperial family's image, where the Empress would be much more involved in a motherly/ceremonial fashion while having no actual political influence, while the Emperor would possess absolute power. Although the philosophy of "Good Wife, Wise Mother" declined in Japan after World War II, feminist historians have argued it existed there as recently as the 1980s.
