Temple (Tome) of General Yue Fei  was built in memory of Yue Fei, he was killed by some bad governor Qin Hui and his followers, people made these bad person`s status in front of Yue Tome and now these bad person are still on their knees and was spit by every person, but now since it`s a part of heritage, so not allowed to do that any more.

So you can see there is a note saying you are not allowed to spit on them.
