As you are currently in China & based on the fact that we have a Double Materials Week just about to start.....my suggestions for the Older Segmented Stories that are worth considering are:
Christmas 2018:
As it does have the repeatable mines called Labyrinth Of Christmas Rings & Chambers Of Christmas Fortune 2018.
As has already been discussed in this forum thread the "Christmas Rings" themselves will not be doubled.
However the materials, coins, gems, precious jewels/stones, ingredients, food items & speed potions will be doubled.
Unfortunately there are no "Beanies" in the repeatable mines so the maximum number of "Beanies" that can be gained via the Story & Challenge Mines is 318.
The best piece of non-gem capacity camp equipment is Donner The Reindeer = 1,132 per slot...requires 103 Beanies....maximum of 4 pieces = 412 Beanies.
The 2nd best piece of non-gem capacity camp equipment is Cupid The Reindeer = 1,072 per slot... requires 60 Beanies...maximum of 5 pieces = 300 Beanies.
The best piece of non-gem regeneration camp equipment is Crystals Of Starlight = 160 per slot...requires no Beanies but needs 10 Topaz...maximum of 3 pieces = 30 Topaz.
The 2nd best piece of non-gem regeneration camp equipment is Crystals Of Fire = 157 per slot....requires no Beanies but needs 30 Ruby....maximum of 3 pieces = 90 Ruby.
The 3rd best piece of non-gem regeneration camp equipment is Crystals Of The Moon = 155 per slot....requires no Beanies but needs 80 Amethyst....maximum of 3 pieces = 240 Amethyst.
Christmas 2017:
As it does have the repeatable mines called Christmas Jewelry Store & Chambers Of Christmas Fortune 2017.
As has already been discussed in this forum thread the "Christmas Rings" themselves will not be doubled.
However the materials, coins, gems, precious jewels/stones, ingredients, food items & speed potions will be doubled.
Unfortunately there are no "Branches" in the repeatable mines so the maximum number of "Branches" that can be gained via the Story & Challenge Mines is 310.
The best piece of non-gem capacity camp equipment is Little Red Riding Hoods Gift = 1,002 per slot...requires 103 Branches....maximum of 4 pieces = 412 Branches.
The 2nd best piece of non-gem capacity camp equipment is Little Red Riding Hoods Tree = 942 per slot... requires 52 Branches...maximum of 5 pieces = 260 Branches.
The best piece of non-gem regeneration camp equipment is Aladdins Gift = 146 per slot...requires 103 Branches...maximum of 4 pieces = 412 Branches.
The 2nd best piece of non-gem regeneration camp equipment is Aladdins Crew = 140 per slot....requires 52 Branches...maximum of 5 pieces = 260 Branches.
They are probably the only 2 Older Segmented Stories worth activating during the Double Materials Week....as they both have the repeatable mines for the Christmas Rings & Chambers Of Christmas Fortunes.
If you haven't done them already you may find some of the Older Stories that cost 500 gems worth it...but most of these do not have repeatable mines so you don't need to rush to buy them for the Double Materials Week.
Hopes this helps you out ๐
