Perguntas sobre exemplo de orações com, e a definição e o uso de "Waka"

Q: I'd like to introduce Waka. She is around 20 years old, my friend's daughter, and bilingual of Japanese and English. My friend worried about me because I'm not good at speaking English in spite of I live in the US so she suggested that Waka became my English teacher and gave online lessons. It was about 30 minutes and once per week. Sometimes we talked a lot so it was about 1 hour. Normally I should pay a high lesson fee for the private English lesson but Waka did it as a volunteer and I could take her lessons for about 8 months. She spent a lot of her free time on my English lessons. Sometimes she sent me the summary of feedback after lessons. I really appreciate her. I think she was a great teacher for me and her lesson was very informative to me. She is very kind and sincere person. She has always been patient with me. I'm sure she will do a great job if she gets a job. soa natural?

Q: Waka requires knowledge of classical Chinese literature and classical Chinese poetry.
By incorporating Chinese classical literature into Waka, I can express a deeper view of the world and emotions.

At present, there are one opinion in Japanese higher education that “Chinese classics are useless and should be abolished from compulsory education”.
Nevertheless, the current Japanese era “Reiwa” is a collection of poems of Waka called "Manyo-shu".
This is the oldest Waka collection in Japan.
Since all the previous eras were sourced from ancient Chinese literature, it became a hot topic that “Ryowa” was "The first era from Japanese literature” in Japan.

For me who studied classical literature in Japan and China, I feel that this atmosphere is a little contradictory.
I want more Japanese people to cherish Japanese culture, literature and history. soa natural?
