no fixed route/schedule/ticket

i (swiss citizen) will be traveling 12 months around the world and do not have a fixed route or plan ticket for china but will most probably cross/travel through china at some point. thus i will not be able to apply for a visa beforehand. in that case can i apply for a 1 year multiple entry L before departing from switzerland without providing a ticket or hotel? if not can i get it at the border/immigration while arriving in china?
