Someone's spittoon, cuspidor?

Laotu's 客廳
Aotu's game parlor
Hannah's 書房

胡學士的講堂
龍少爺的藏金閣/藏嬌屋
豬姑娘的化裝間
戲雨鷹的後花園

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

愚公的滯留地
"封過"的墓基...

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