Ask to recommend a good building materials information price inquiry software?

At present, there are many software to check the price. If the landlord inquires about the information price, you can use Blu-ray Building Materials Cloud. There is a one-week probation period after registration, which is available in all provinces and cities. Moreover, the information price of prefecture-level cities in the first seven or eight years is complete, including supplements, as well as the national building materials market price and seedling market price. If it is opened later, it will take hundreds of years, which generally meets the requirements of the landlord.
