Y diwrnod oedd yn oer, gyda'r eira newydd yn claddu strydoedd Caerdydd.

The day was cold, with the fresh snow burying the streets of Caerdydd.

Ystod y Gaeaf, roedd busnesau teuluol fel un Gareth yn brwydro i oroesi mewn byd sy'n newid yn gyflym.

During the winter, family businesses like Gareth's were struggling to survive in a rapidly changing world.

Roedd Gareth, entrepreneur profiadol, yn cadw pwyslais ar drefn draddodiadol.

Gareth, an experienced entrepreneur, maintained an emphasis on traditional order.

Ond roedd ei ferch, Rhian, yn gweld y posibiliadau newydd cyflwyno gan farchnadoedd digidol.

But his daughter, Rhian, saw the new possibilities offered by digital markets.

Rhian oedd yn ffrind i bob teclyn a gwahanol raglenni cyfrifiadurol, y fath oedd caru technegau newydd a'r datblygiadau cyffrous a ddigwyddai yn y Welsh Tech Hub.

Rhian was a friend to every gadget and different computer programs, loving new techniques and the exciting developments happening at the Welsh Tech Hub.

Roedd ganddi syniadau gwyllt, yn llawn gweledigaethau i weddnewid busnes y teulu, ond collodd amynedd pan nad oedd ei dad yn gweld y byd drwy'r un lens wag.

She had wild ideas, full of visions for transforming the family business, but she lost patience when her father couldn't see the world through the same open lens.

Rhwng y ddau oedd Emrys, brawd Gareth, yn trio sicrhau bod heddwch yn y teulu.

Between the two was Emrys, Gareth's brother, trying to ensure peace in the family.

Roedd diwrnod San Ffolant yn nesáu, ac roedd Rhian wedi cynllunio i chwalu ei meddyliau ar y bwrdd mewn ffordd penodol.

Diwrnod San Ffolant (Valentine's Day) was approaching, and Rhian had planned to spread her ideas on the table in a specific way.

Paratôdd gyflwyniad cudd, gan obeithio gyrru’i dad i weld mantais digideiddio.

She prepared a hidden presentation, hoping to drive her father to see the advantage of digitization.

Ond, trwy y nosweithiau oer, roedd croesair arall gan Gareth, yn ystyried gwerthu'r busnes i osgoi sgarmes.

But, through the cold evenings, there was another concern for Gareth, considering selling the business to avoid a skirmish.

Gyda'r prynhawn wedi cyrraedd, roedd yr adeilad yn Hwb Tech Cymru yn frwd o egni.

As the afternoon arrived, the building at the Hwb Tech Cymru was buzzing with energy.

Rhoddai'r ystafelloedd gwydr brafddelwedd uwch-dechnoleg, gyda sŵn bywiog syniadau newydd yn gyson.

The glass rooms gave off a high-tech image, with the lively sound of new ideas constantly present.

Yn eu cyfarfod teuluol, roedd y tensiynau'n uchel.

In their family meeting, tensions were high.

Rhoddodd Rhian ei chyflwyniad, yn syllu'n benderfynol i lygaid ei thad.

Rhian gave her presentation, staring determinedly into her father's eyes.

"Gweler," meddai hi, "dyma’r dyfodol."

"Look," she said, "here is the future."

Roedd emosiwn yn ystwytho wrth i'r gwirioneddau personol ddod i'r golwg.

Emotion shifted as personal truths came to light.

Gareth yn edifarhau, "Nid wyf am golli'r hyn a adeiladwyd gan ein cynhefsydd.

Gareth lamented, "I don't want to lose what was built by our ancestors.

Ond, dydw i ddim eisiau diystyru’r dyfodol chwaith."

But, I don't want to disregard the future either."

Cafodd Emrys faes sefydlog ar y bwrdd: “Pam na allwn geisio gychwyn ar brosiect peilot?

Emrys found a stable ground at the table: “Why can't we try to start a pilot project?

Rhian, gad i ni weld y pwerau newydd.

Rhian, let us see the new powers.

Gareth, byddaf yn monitro ym mhob cam.”

Gareth, I will monitor every step.”

Cafwyd cytundeb.

An agreement was reached.

Cytunodd Gareth i roi cynnig ar syniadau Rhian, gyda'r tri ohonynt yn sylweddoli pwysigrwydd cydweithio.

Gareth agreed to give Rhian's ideas a chance, with all three of them realizing the importance of collaboration.

Yn y diwedd, roedd Gareth wedi ehangu ei orwelion, yn derbyn newid fel cwreiddyn newydd, tra Rhian wedi dysgu gwerth amynedd wrth gyflwyno syniadau newydd.

In the end, Gareth had broadened his horizons, accepting change as a new foundation, while Rhian learned the value of patience when introducing new ideas.

Gyda Emrys yn ennill mwy o hyder, roedd ganddo bictiwr o’i rôl fel arweinydd yn tyfu.

With Emrys gaining more confidence, he had a growing picture of his role as a leader.

Roedd eira’n parhau i gwympo y tu allan, ond o fewn yr hwb, roedd y teulu wedi dod o hyd i ffordd newydd o symud ymlaen, gyda thraddodiad a’r arloesedd yn cyd-fyw.

The snow continued to fall outside, but within the hub, the family had found a new way forward, with tradition and innovation coexisting.

Roedd yr arwyddion o ddyddiau gwell iawn i ddod.

The signs of much better days were very evident.
