Question: The carnival of Guido Maus's birth place is linked to a European culture. In the era of Rotrude's father the language of that culture was later referred to by what name?

Knowledge 1: Guido Maus
Guido Maus (born 5 November 1964, Malmedy) is a Belgian-born gallery owner, gallerist, curator, and long-time collector of contemporary art currently living and working in Birmingham, Alabama. [SEP] Knowledge 2: Carnival
The Carnival of Malmedy is locally called Cwarmê. Even if Malmedy is located in the east Belgium, near the German-speaking area, the Cwarmê is a pure walloon and Latin carnival. The celebration takes place during 4 days before the Shrove Tuesday. The Cwarmê Sunday is the most important and insteresting to see. All the old traditional costumes parade in the street. The Cwarmê is a "street carnival" and is not only a parade. People who are disguised pass through the crowd and perform a part of the traditional costume they wear. The famous traditional costumes at the Cwarmê of Malmedy are the Haguète, the Longuès-Brèsses and the Long-Né. [SEP] Knowledge 3: Rotrude
Rotrude (or sometimes referred to as Hruodrud/Hruodhaid) (775/778 – 6 June 810) was a Frankish princess, the second daughter of Charlemagne from his marriage to Hildegard. [SEP] Knowledge 4: Middle Ages
Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,[M] allowing a common writing style that advanced communication across much of Europe. Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. New works on religious topics and schoolbooks were also produced. Grammarians of the period modified the Latin language, changing it from the Classical Latin of the Roman Empire into a more flexible form to fit the needs of the church and government. By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin.

It is not known where or when Li Kening was born, but it is known that he was Li Keyong's youngest brother and therefore would have been born after 856, when Li Keyong was born. Their father was the ethnic Shatuo general Li Guochang, whose name was originally Zhuye Chixin but was later bestowed the Tang Dynasty imperial clan name of Li and a new name of Guochang, but because Li Kening's birth year is unknown, it is not known whether he would have been born with the name of Li or Zhuye. He was said to be kind and filially pious, and (despite his eventual fate) described to be the most virtuous among Li Keyong's brothers and cousins.
