China's women made it three victories out of three to top the pile at the World Curling Federation's Olympic Qualification Event in Pilsen.
The side skipped by former world champion Bingyu Wang preserved their 100 per cent record with a pair of wins at the Winter Arena Košutka in the Czech city.
They first demolished Finland 9-0 before backing that up with a 11-5 win over Latvia.
"We hope we can get this dream," said Wang.
"We need to play better and have more patience and confidence."
Denmark also boast a 100 per cent record in Pilzen but have only played twice.
They won their sole game today against Germany, 9-7.
None of the other five countries involved at the event so far have a winning record.
In the men's tournament there is a four-way tie at the top of the round-robin.
China, Denmark, Germany and Italy all boast a record of two victories and one defeat.
The other four sides competing, Czech Republic, Finland, The Netherlands and Russia, have all won once and lost twice in a tight group.
Denmark enjoyed a good day with two wins, 5-3 against China and 10-4 against the Czechs.
Germany also managed a pair of successes, beating the host nation 8-4 and then seeing off the Dutch 4-3.
"That is a big one," said Danish skip Rasmus Stjerne after the win over the Chinese.
"China were the front runners.
"If we forfeited this one we would have been in the bottom, but right now we keep it close.
"Every win is important.
"[It took] a really good team effort to win this game.
"They weren't sharp and we took advantage of that."
Russia endured a day to forget as they lost 6-5 to Italy and 9-6 to Finland.
The Dutch beat the Finns 8-4, with China seeing off the Italians 10-5.
Action continues at the event tomorrow.
Round-robin play will be held until December 9, with the top three teams in both the men's and women's tournaments progressing to a page play-off system.
This will see the round-robin winners face the second place side with the triumphant team earning a place at Pyeongchang 2018.
The losers of this clash will take on the third-placed side for a second Winter Olympic spot.
