English names are usually first name middle name(s) last namw. There is only one first name, and there is only one last name. middle name is the middle name, there can be multiple, but most of them only have one. Moreover, Chinese names usually only have three parts at most. Such a long name is meaningless and cannot be used for addressing or writing.
In addition, Richard is a male name and cannot be used as a surname. Moreover, people from non-English-speaking countries do not change their surnames when given English names. The surname remains the original surname. If the native language is not written in Latin letters, it will be Latinized, and there is no need to find an English surname. Secret is an ordinary word and does not have a name with the same spelling, so it is not suitable for use as a middle name.
So just change it to Christina Olivia, the Latinization of the Chinese surname. Another thing to note here is that Christina is a name with obvious Christian overtones. If your aunt is not a Christian, it is not recommended to give your child this name.
