A Nigerian teacher was sent to China to teach.... The first day he entered the class and was roll calling,

He called out a name, "Sheng", a student stood up and answered "present sir".
He called the second name "Chu Muon ", another student answered "present sir".
.
Suddenly he sneezed "Hatchia". One student seated at the corner stoop up and said, "present sir".
.
He surprisingly exclaimed, "Hmmm". All the students shouted "Absent sir".
.
At this moment, he got confused and said, "Chai". Three students immediately stood up and said, "Which of us sir?".
.
The teacher became even more confused and asked, "What is wrong?"
A student stood up and answered," Sir, I am not wrong. I am called Wong " Now the teacher could not help it but laughed out, " Hahahaha" A girl stood up and answered, "present sir"
The teacher collapsed in laughter.

Enjoy your day.
