International to Domestic Connetion - Luggage Transfer, Boarding Pass & Security Check in PEK,

We plan to arrive on May 8, 2016 from Vancouver by Air Canada Flight AC 29 and our connecting flight is Air China Flight CA 1469 to Lijiang. Flight from Vancouver AC 29 arrives at 14:10 and flight o Lijiang CA 1469 departs at 16:20. Do we have sufficient time? Do we have to gather our baggage after customs clearance and recheck them with Air China? I am told the baggage will be checked directly to Lijijang. Do we have to go through the Security for the Domestic Flight with all others or is the a special security check, presumably with shorter line, for the International Passengers transferring to Domestic flights? Also do we have to get Boarding Pass from Air China.
