Its R&D profile includes five engineers, new products in the past year, ODM, OEM for popular brands, and multiple customization modes.

Limitations include no SDK, overseas warehouse, overseas showroom, overseas agents or branches, and no stated implementation of AI-supported sustainable-development management. Financial credibility cannot be determined from the provided slices because only reporting years are listed, without financial performance or balance-sheet figures.
