Should new buildings not be constructed in historical city centres or downtowns?

I think there should be careful limits on new construction in historic areas. The main risk is losing the character that makes these places special - like in Shanghai's old French Concession, where the tree-lined streets and historic buildings create a unique atmosphere. If developers built modern high-rises there, it would completely change the neighborhood's charm. That said, cities do need to evolve, so perhaps the solution is to require new buildings to blend with the existing style. For example, near West Lake in Hangzhou, I've seen some new developments that use traditional architectural elements while still being modern inside. It's about finding that balance between preservation and progress.
