Dare to Act – Act Fast – Act Solidly

In the land of Thanh Hoa – a region that has given birth to many decisive milestones in the nation’s history – the Ho Citadel stands majestically as a stone declaration of the will to act and organizational capacity beyond its era. Built in 1397, in just 3 months, this colossal stone citadel was not only the capital of Đại Ngu, but also a rare testament to the Vietnamese people’s ‘think big – act fast – build solid’ mindset in the late 14th century.

This spirit, when placed in the context of modern industry, finds clear parallels with Dongyang (DY Corporation) – a Korean industrial group embodying a strong, pragmatic, and action-oriented philosophy.

Ho Citadel – A Stone Architectural Marvel of Willpower and Speed

The Ho Citadel (also known as Tay Do, Tay Kinh, An Ton) is located in Vinh Loc district, Thanh Hoa province. It is one of the very few large stone citadels still existing in the world. In 1400, the structure became the capital of Đại Ngu under the Ho Dynasty.

What makes the Ho Citadel a marvel is not just its scale, but also how it was created:

Massive stone blocks weighing tens of tons

Precisely carved and chiseled

Stacked tightly without the need for mortar

Completed in an extremely short time: 3 months

Construction Mindset Ahead of Its Time

In the context of manual craftsmanship, the transportation, lifting, and precise installation of these colossal stone blocks demonstrate:

Superior labor organization capabilities

Pragmatic and optimized engineering mindset

Political determination and decisive action

Without elaborate decoration or soft symbolism, the Ho Citadel possesses a raw – robust – direct beauty, accurately reflecting the spirit of a turbulent historical period that demanded strength and decisiveness.

It is this value that led UNESCO to recognize the Ho Citadel as a World Cultural Heritage site in 2011, affirming the structure’s special position in the history of human architecture.

Dongyang (DY Corporation) – The Power of Pragmatic Industrial Thinking

If the Ho Citadel is a symbol of ‘achieving great things in a short time,’ then Dongyang – DY Corporation is the embodiment of that spirit in modern Korean industry.

Starting from a Core Technical Foundation (1978)

DY Corporation, formerly Dongyang Hydraulics, was founded in 1978 in Changwon – the heavy industry hub of South Korea. From the outset, DY focused on hydraulic equipment – a field that demands:

High durability

High load capacity

Absolute precision and stability

In 1989, DY was listed on the Korea Exchange (KRX), marking a transition to a modern management model and expansion of production scale.

Rapid Expansion – Direct Market Entry (1990–2005)

During its growth phase, DY did not spread itself thin but directly targeted international markets:

Established branches in China and Japan

Achieved international quality certifications such as ISO/TS 16949

Consistently won export awards for 70 million USD and 100 million USD

This was the period when DY clearly demonstrated its philosophy: Products must perform – and must be marketable globally.

Restructuring for Greater Strength (2006–2014)

DY established specialized companies:

DY POWER – hydraulic equipment

DY AUTO – automotive components

In 2014, the company officially adopted the name DY Corporation, reflecting a multi-sector strategy with a focus on core technology, while simultaneously increasing R&D investment and standardizing production.

Acting for a Sustainable Future (2015 – Present)

Since 2015, DY POWER successfully IPO’d, expanding into Mexico and China, gradually reaching North America and Asia. In recent years, DY has focused on:

Digital transformation

Mechatronics development

Electrification technology

Sustainable, environmentally friendly production

DY does not build a flashy image, but consistently adheres to its core values:
strong – durable – truly effective.

Intersection of Values: The Power of Decisive Action

Between the Ho Citadel and Dongyang, there is a consistent commonality:

Once a task is undertaken, it must be done quickly – and it must be done solidly.

The Ho Citadel chose large stones, simple structure, and rapid construction

Dongyang chose hydraulic technology, pragmatic design, and optimized performance

Both do not boast about their form, but focus on the ultimate outcome: standing firm against time and pressure.

May’s Message – Action Creates Miracles

Ho stones embody the strong will of the Southern people
Dongyang lifts beyond countless obstacles.

May is a reminder of the spirit:

Dare to act

Act fast

Act solidly

Because in both history and modern industry, miracles do not come from hesitation, but from right and sufficiently strong action.
