First of all, I suggest you call 114 to find out which big decoration companies are there in the local area! Make a comparison! Let yourself know the number! Then, you can book a visit to the poem-raising boat stream to go to the local community being renovated, and visit the owners&; homes being renovated. You can ask others more and see which decoration companies have better reputation and workmanship! Only when you go to the actual investigation can you understand it more clearly! This is for the best.
