Fun Day

It is so hot in Sanya, China. I had classes from 8 AM to 12 noon today. I am sooooo...tired but it was fun. My language partner shared a picture of the super moon with me. It was very pretty. After lunch I went to my part-time job, which is teaching Chinese for a primary school student. It's so cool.

Your message was very clear. You wrote about your morning in class and then your afternoon tutoring. 

1 - If you taught an entire class (not just one student) you need to use plural form (students) to make that clear. 

2 - It is unclear if your partner showed you one photo. So, either replace the with a or use plural the form pictures.

3 - It is not necessary to include both after lunch and afternoon. if you talk about something that happens after lunch the reader will understand it is during the afternoon.
