I know nothing about Spring Festival before doing my homewor

I know nothing about the Spring Festival before doing my homework.As far as I know,the Spring Festival is only about lucky money and the reunion meal with my family.I have found a lot of information on the Internet,so I know different countries have different customs.For example,in America,people enjoy champagne when they celebrate their holidays.

有。时态。还有些表达不妥。

时态，know 改为 knew

on the Internet改成from the Internet会更好，但是用on没有错。应该是when they celebrate their festival.
