Read his sentence order. His wife was caught retrieving money from bank
account under organizations such as NED many times.
Liu started copy+pasting articles 20+ years ago, but he got sentenced
now because he has been receiving money from NED. Check what NED does (not
from their own website, read comments.) Basically it's a secret agancy of U.S
government to promote "revolution" in other countries and help overthrow other countries' government.
He is a "hero", because he chose to stay in China? Well it is obvious his
investment is worth something. But would a hero of Chinese poeple receive
money/funding from NED? I know I wouldn't call this person a hero. He
receives money, and he did his job---basically, copying+pasting articles to
embarrass CCP.
