OUT1: focus on local, does not focus on the overall 
 Some designers to focus on home improvement local, but to grasp the whole. This makes it just look at a local can also, but the integrity and practicality is not satisfactory. In terms of design, "Unity in Diversity" in principle from the actual results, the home improvement design should not be everywhere at home, make a fuss about the "crowning touch" to be carefully crafted, the overall feeling full is the best article . " "Local good, cook a meal as a whole" has been the difficulty of the artists and home design, the designers focus on the overall design. 
 OUT2: suitable for the general public, is not suitable for this one " 
 Decoration company personnel to the stratification of the level of decoration design design objects, they usually think, engaged in the design is the "top" design for the rich; located in the "white collar", "big house", the design grade , and vice versa. In fact, this is a misunderstanding. Home improvement design as the other arts, the decision level, not the content but the "performance" decision level. 
 OUT3: pay attention to color, but do not pay attention to color relations 
 Recent visit, some home improvement finished, found that some designers only pay attention to the color itself, the property in the home Color Design, and less attention to the color contrast between the decoration of the overall effect more than a few defects. For example: the identified living room with the yellow color is warm there is affinity, but also that the study to be quiet, blue, etc., but did not pay attention to the color relations between the living room warm and the study of cold, did not consider the overall tone of the full set of home improvement color sense. Therefore, designers should improve the color of the ability to grasp.
