Social Media
Social media platforms like Pinterest, Instagram, Facebook, Twitter, and Snapchat have all been banned. Twitter got the ban in 2009, but there are over 10 million registered users from China. Oftentimes, citizens use virtual private networks to access the sites that the country has banned. Gotta be careful, though.
Bowing to Your Elders
Bowing to your elders is customary in many Asian cultures. Most cultures have a "respect your elders" state of mind, but the Chinese are known for taking great care of their elderly family members. In fact, there is a law in China called the Filial Piety Law which states that adult children are expected to support their parents who are 60 years and older.
