It's time to make final guess and elaborate .
Short Track Speed Skating: Men's 500m/1500m and Mixed relay with decent chance to win medals even gold medals. Women's and Men's relay are always with chance given the messy situation. To be realistic and consider the unpredictability of the discipline, 2 golds and 6 medals.
Speed Skating: Men's 500m and 1500m are among gold medal contenders but with plenty rivals from US, Canada and always Netherland, also Men's 1000m also with slim chance of medal. As host, I decide to be a little optimistic, 1 gold and 2 medals.
Figure Skating: Though Russian show great competence on ECH, Chinese pairs can win the gold if skate cleanly for both short and free programs. Also China also have slim chance on team event to win a bronze medal. Once again I'm optimistic as host, 1 gold and 1 medal.
Freestyle Skiing: Aerials are quite unpredictable, Mixed team with greatest chance to win gold medal, Women's and Men's event are almost guaranteed with medals but the color is hard to predict. Super star Gu Ailing almost secures the Halfpipe gold, and also with 50% to win Big Air and 20% to win Slopestyle. In total I would guess, 3 golds and 6 medals.
Snowboarding: Su Yiming proved his ability on Big Air already. And I see great potential on his Slopestyle, hopefully he succeed Backside 1980 on OG. And Cai Xuetong has capability to win a medal even though she can't compete Chloe Kim. 1 Gold and 2 medals.
Skeleton/Bobsleigh/Curling: Hopefully at least one of these sports can make some surprise. 1 medal.
My guess: 8 golds and 18 medals
Pessimistic guess: 6 golds and 15 medals
Optimistic guess: 10 golds and 20 medals
