Shanher’s offshore diving suit.  
In order to ensure the underwater tightness, the main body of the diving suit is worn by pouring, which is complex and difficult. Therefore, shanher is generally carried on board after completing the installation of a full set of equipment on land before going to sea.  
First, she needs to wear a waterproof latex lining and lie in a special mold. Then the mold is closed and injected with latex. After the latex solidifies, the lining of the diving suit will be formed, so that all parts except the head will be covered by latex. The crotch of the diving suit does not use a reserved opening or catheter to facilitate excretion when wearing, but fills the lower body with biological latex to decompose excreta. In the mold, shanher’s arms will be folded and fixed by latex, and the gap between the legs will be filled with latex. The only difference from Mermaid gel coat is that it is separated below the ankle. In the previous swimming test, shanher’s whole tail fin is not conducive to flexibly changing the body posture in the water, so in the diving suit scheme, it is changed to separate feet to install fins in the later stage, so that the posture control in the water is more flexible, so it looks more like a seal than a mermaid. It is also more convenient to get on and off the boat with separate feet (although shanher can hardly climb on the boat by herself after her arms are folded and bound together).  
At the same time, the diving suit will not transform the body structure, so shanher’s original dragon tail has been retained. Although it seems cumbersome, the actual effect in the water is much better than it looks. The tail also plays a certain auxiliary role when the legs push the body forward.  
After wearing the lining, shanher also needs to wear a layer of outer lining for underwater warmth preservation. The wearing method is ordinary rear zipper, but there is still latex interlayer on the inner side, which will adhere to the lining after wearing, so as to ensure the absolute fit of the diving suit.  
Because shanher has been trapped by the lining, someone needs to help her put on the outer layer. After the installation of fins and pectoral fins, the main body of the diving suit is basically worn. The helmet of the diving suit Baotou does not have a transparent window, because considering the dark light in deep water, the helmet replaces the transparent lens with sonar and inner display screen. At the same time, the helmet also has a simple camera imaging module, which can meet her basic vision when she is on the water.  
The respirator on the mouth of the helmet is in the shape of a 10cm fake penis, so shanher can’t speak after wearing the helmet.
