to buy a ticket for an itinerary like this, you may have to contact the airline or use a lesser-known aggregator.
para makabili ng tiket para sa isang itineraryong tulad nito, maaaring kailanganin mong kontakin ang airline o gumamit ng hindi masyadong kilalang aggregator.

for instance, most aggregators are not selling tickets from china to the united states (presumably to avoid falling afoul of restrictions and being on the hook for a passenger's flight out).
halimbawa, hindi nagbebenta ng ticket mula china papuntang united states ang karamihan ng mga aggregator (ipinapalagay na para makaiwas na pagbawalan at maging kawit para sa paglipad palabas ng pasahero).
