How does mr. wang greet miss li? this is for my chinese class. how do you write it in chinese

Usually it would be 你好（ni hao) but if it is a very formal situation and the two people have distance between their relationship, he could say 您好(nin hao). however, 您好 is generally used more when talking to the elderly or of people who have a lot more authority than you (like speaking to a government member or something haha- it isn’t as commonly used than ni hao, but both are acceptable)

What does this mean sorry i speak only english

Students and school are nouns
good luck!
