The meaning of “Lu + Ke”
Lu means wealth/profit, Ke means qualification & reputation. “Lu+Ke”= get the qualification first, then make the $$$ afterwards. For example: the occupation of teacher, accountant, engineer and doctor etc. —– this is from wealth and career points of view.
For peach blossom: because Lu & Ke are not in the same group of Si-Hua, so it means many. And also the “class” of the peach blossom is high, it’s enjoyable.
