What does this phrase in Yue Fei Temple mean? (Characters identified: 忠孝千秋) Most of the phrases put up in Yue Fei Temple are easy to read, but this one is in Seal Script and I can't figure it out. I know the first character to be 忠, but the others I can't figure out. On the left I can see this was made in the winder of 2012, but I can't find out any information on google about this.
It is 忠孝千秋 (Thanks to the link Johan88 provided)
 = 忠
 = 孝
 = 千
 =  秋 (The image from the site used 秌, which is an older version of 秋. The people who made the plaque used the 秋 modern Chinese use )
