Good day, Jenna I just want to add own thing to the corrections below. It's 晚上好 wǎn shang hǎo. 上 is originally read as the fourth tone, it means to go; for example 上課 shàng kè (to have a class) , 去上班 qù shàng bān (to go to work). It can also be read as the neutral tone / light and quick tone (no tone mark); for example 車上 chē shang (in the car), 早上 zǎo shang (in the morning). Hope they help. Regards, Terecia

你好，晚上好
