Pretty much the same, I guess.It is republican era, opera etc. Only in Farewell concubine it is BL. Winter Begonia is based on a bl novel but it's bromance( a cute one hehe)

Guardian is about ten thousand year of love.Shen Wei and Yun Lan's relationship is unique in everyway. In The Lost Tomb Kylin Zhang is Wu Xie's protecting angel and their relationship is as unique as theirs. :') If you want to watch something like Guardian this drama is the best, I think.
