What is claimed is: 
     
         1 . A child resistant bag, comprising a bag body, a first wing and a second wing that are arranged at two sides of an inlet of the bag body, wherein the first wing comprises a first strip, and an upper wing and a lower wing a connected to two sides of the first strip, the second wing comprises a second strip and a lower wing b connected to a lower side of the second strip, the upper wing and the lower wing a are both connected to an inner wall at the inlet of the bag body, the lower wing b is connected to the other inner wall at the inlet of the bag body, the first strip and the second strip are arranged correspondingly, the first strip and the second strip are press-fitted to each other so that the bag body is sealed automatically, a gap is provided between one side of the upper wing and the inner wall of the bag body to form a finger extension area, and a sealing structure is provided between the upper wing and the bag body and within the finger extension area. 
     
     
         2 . The child resistant bag according to  claim 1 , wherein the sealing structure comprises a fake sealing structure formed between the upper wing and the bag body and within the finger extension area. 
     
     
         3 . The child resistant bag according to  claim 2 , wherein the fake sealing structure is formed by using a fake sealing process. 
     
     
         4 . The child resistant bag according to  claim 2 , wherein the fake sealing structure is formed by gluing. 
     
     
         5 . The child resistant bag according to  claim 1 , wherein the sealing structure comprises a true sealing structure formed between the upper wing and the bag body and within a finger extension area, the upper wing has a cutting line provided along a length direction of the upper wing, and the cutting line passes through the finger extension area and is positioned below the true sealing structure. 
     
     
         6 . The child resistant bag according to  claim 5 , wherein the true sealing structure is formed by using a heat sealing process. 
     
     
         7 . The child resistant bag according to  claim 5 , wherein the cutting line is formed by die cutting or continuous cold cutting through a hob. 
     
     
         8 . The child resistant bag according to  claim 5 , wherein a cutting depth of the cutting line is ½ to ⅔ of a thickness of the upper wing. 
     
     
         9 . The child resistant bag according to  claim 5 , wherein the cutting line is a dotted straight line. 
     
     
         10 . The child resistant bag according to  claim 5 , wherein the cutting line is a dotted fold line. 
     
     
         11 . The child resistant bag according to  claim 5 , wherein the cutting line is a dotted curved line. 
     
     
         12 . The child resistant bag according to  claim 1 , wherein the inner wall of the bag body has an embossed relief pattern. 
     
     
         13 . An opening method of a bag, comprising the following steps:
 S1, pulling apart an upper wing and a bag body at a fake sealing structure, and exposing a finger extension area;   S2, extending a finger of one hand into the finger extension area and gripping one side of a mouth of the bag body, then gripping the other side of the mouth of the bag body with a finger of the other hand, and keeping the fingers of the two hands at force points of a same height; and   S3, forcibly and simultaneously pulling apart the bag body by two hands towards opposite directions.   
     
     
         14 . An opening method of a bag, comprising the following steps:
 S1, flipping over a mouth of a bag body, and bending an upper wing at a cutting line within a finger extension area;   S2, scratching the cutting line with fingers, extending a finger into the finger extension area and gripping one side of the mouth of the bag body;   S3, gripping the other side of the mouth of the bag body with a finger of the other hand, and keeping the fingers of the two hands at force points of a same height; and   S4, forcibly and simultaneously pulling apart the bag body by two hands towards opposite directions.
