This Part 2 Episode 19 scene showed Huang YaoShi played his Jade Flute to call out Huang Rong. In his background by the north end window, there were 3 wine flasks on top of a table.
Grew out of frustration, Huang YaoShi began smashing wine flasks, tables and stools in the wineshop. The 3 wine flasks by the north end window is now down to 2. But he was never near the north end of the window to pick one up. Those wine flasks on the ground were from the table where he's leaning now.
