Modern style: The architectural elements of modern style include reinforced concrete, large amounts of glass, metal materials, etc., which are not suitable for traditional retro buildings.

Bright colors: Retro Taiwanese temples typically use antique color tones such as red, black, gray, gold, etc., so bright colors would appear too vivid and abrupt.

Minimalist style: The architectural elements of minimalist style include simple lines and plane design, which do not match the intricate carvings and details of retro buildings.

Elements commonly found in modern architecture such as steel, concrete, and glass are also not suitable for appearing in retro Taiwanese temples.

A large amount of relief and three-dimensional decoration is also not suitable for appearing in retro buildings, as this would make the appearance of the building too complex and cluttered.
