05 Write at the end
Rosewood has excellent materials and pleasing color patterns, and the furniture it makes has been loved by the general public, especially the new Chinese furniture that combines tradition and fashion, which occupies a considerable proportion of sales in the market, so there are various furniture called "huali".
