One week before the national holidays in China tickets to Germany where quite expensive, probably around 1500 Euro for a flight from Beijing-Frankfurt during the holidays.

For the next Christmas holiday period I booked my flight now already and only had to pay about 320 Euro without tax (I think, including tax the ticket will cost around 400 Euro).

My accountant called the travel agency twice just to make sure that it is really a round-trip, not a single-flight.
