Chinese-made copper-cast carved clocks have become popular at home and abroad with great value in appreciation, usage and collection.

Dongchang copper casting and carving technique, a provincial intangible cultural heritage, has a history of more than 300 years in Liaocheng, East China's Shandong province.

Ma Xianming and Ma Xianmin, inheritors of this intangible cultural heritage, established a company making western-style and antique clocks.

With years of exploration, experience accumulation and market research, they made improvements in their research, development and design, as well as their clock-making craftsmanship.

They not only revived traditional clock-making techniques in the modern age but also spread these artistic products internationally.
