Name origin of the days of the week, the twelves months, and the twelve Chinese years

Hello everyone, my name is Joseph. I am a homeschooled high school junior from China yet taking an American program. I am the Founder and Moderator of the Reading and Writing Subworld. On Schoolhouse, I like to tutor English literature, ancient history&culture/mythology, Chinese, and community events. My sessions are full of joy and laughter because I like to insert games into my session and I enjoy chatting with my learners about anything. My best subjects in school are history, geography, and English, but please do not ask me to tutor you in STEM, that is my weak spot. I played the instrument Hulusi (gourd flute) a traditional Chinese instrument and reached the top level in 2022; I also have fundamental knowledge of piano and the Chinese bamboo flute. I also make a lot of art with ink pen and gouache. I have been attempting digital art recently and really enjoyed it! In my free time, I also play video games; I am a huge Honor of Kings fan :) I am a very active tutor on Schoolhouse and I love to make friends! Feel free to reach out with anything you might need help with and I am willing to lend a hand if it is within my power.
