Someone's spittoon, cuspidor?

Laotu's 客厅
Aotu's game parlor
Hannah's 书房

胡学士的讲堂
龙少爷的藏金阁/藏娇屋
猪姑娘的化装间
戏雨鹰的后花园

123's sauna
sigma's skating ring (非也!)
高知度的舞台
waitGC's repartee joint

The-overworked's pressure cooker outlet
The-down-but-not-outs' psychologist's couch

愚公的滞留地
"封过"的墓基...

Unfortunately, it is also someone else's spittoon, cuspidor....
