QUESTION ABOUT THE RUSSIAN LANGUAGE!! Can someone tell me they sentences I should use 'мой' and 'моя'. Please give examples for each!

Iwill give all da points. imagine you are working for the u.s. branch of a chinese trading company. this trading company mainly trades chinese traditional art crafts and related items (such as chinese paintings and chinese music instruments). this week, your company had a promotion event, and a lot of goods were sold. now that the event is over, your manager asks you to write him a report in chinese. in this report, you are required to include: description of the chinese traditional art items being sold, their attributes such as colors and amount sold; price for each type of goods, and the total profit, in both chinese and u.s. currencies; your manager needs you to give an overall evaluation about what the most and least popular items are, and how people reacted to this promotion event – whether they liked this event or not. write as much as you can in chinese characters. it can be super simple btw

Is the or in survivors a prefix or a suffix? ?

Castor et pollux, fratres, in multis bellis magna virtute pugnabant et multos hostes superaverunt. olim magna tempestas (storm) ad navem appropinquabat (came near), sed auxilio deorum discessit. tum nautae in capitibus castoris et pollucis duas stellas viderunt. "dei ipsi in capitibus fratrum has stellas posuerunt," omnes clamaverunt. "fratres boni sunt causae salutis nostrae! " postea acer hostis castorem interfecit et hic ad inferos (underworld) properavit (hastened). maximus dolor pollucem occupavit, sed is erat immortalis (immortal) quod filius dei erat. sine fratre suo pollux erat miserrimus et tristis. pollux ex patre deorum ipso oravit, "ego laetissime vitam meam," dicit, "pro fratre meo donabo." iuppiter autem dixit se castori unum diem vitae, polluci unum diem mortis donaturum esse. itaque locum fratrum cotidie (daily) mutavit. iuppiter duas stellas in caelo locavit. homines fratres geminos (twins) appellabant. do not use google i will not give you and i will report your question if you do use google translate. seventy points!
