Input: proper question: The mother of which emperor was a concubine?

 context: Since its invention in 1269, the 'Phags-pa script, a unified script for spelling Mongolian, Tibetan, and Chinese languages, was preserved in the court until the end of the dynasty. Most of the Emperors could not master written Chinese, but they could generally converse well in the language. The Mongol custom of long standing quda/marriage alliance with Mongol clans, the Onggirat, and the Ikeres, kept the imperial blood purely Mongol until the reign of Tugh Temur, whose mother was a Tangut concubine. The Mongol Emperors had built large palaces and pavilions, but some still continued to live as nomads at times. Nevertheless, a few other Yuan emperors actively sponsored cultural activities; an example is Tugh Temur (Emperor Wenzong), who wrote poetry, painted, read Chinese classical texts, and ordered the compilation of books.
