1. A mixing valve assembly comprising a mixing valve including a valve body having: a first rotating element connected to a valve stem for turning on and off said mixing valve, and for adjusting outlet water temperature of said mixing valve; and a first mark on said first rotating element; and a second rotating element being an integral part of a water-tight enclosure of said mixing valve, maintaining a water-tight seal of said water-tight enclosure while being rotated, and forming said water-tight enclosure that envelopes said valve body of said mixing valve, covers a hole in a shower wall thereto said valve body penetrates, and prevents water leakage to a hidden area behind said shower wall; and a second mark on said second rotating element; wherein: a relative movement between said first and second marks occurs when said first rotating element is rotated; and said mixing valve is capable of presetting said outlet water temperature to a desired water temperature by, firstly, rotating said first rotating element to a stop position corresponding to said desired water temperature, and secondly, rotating said second rotating element to a stop position where said second mark meets said first mark; and said mixing valve is capable of retrieving said desired water temperature after said mixing valve being pre-set to said desired water temperature, in which, said first rotating element is rotated to a stop position where said first mark meets said second mark. 2. The mixing valve according to claim 1, in which, said mixing valve is provided with a locking means so that an escutcheon is securely attached to a wall without requiring screws. 3. A mixing valve assembly comprising a mixing valve including a valve body having: a first rotating element connected to a valve stem for turning on and off said mixing valve, and for adjusting outlet water temperature of said mixing valve; and a first mark on a stationary element of said mixing valve; and a second rotating element that is rotatably connected and threadedly engaged to said first rotating element, rotatable about the axis of said valve stem, and forming an integral part of a water-tight enclosure that envelopes said valve stem; and a second mark on said second rotating element; wherein: no relative movement between said first and second rotating elements occurs when said first rotating element is rotated, but, a relative movement between said first and second marks occurs when said first rotating element is rotated, a relative movement between said first and second marks occurs when said second rotating element is rotated, and a relative movement between said first and second rotating elements occurs when said second rotating element is rotated; and said mixing valve is capable of pre-setting said outlet water temperature to a desired water temperature by, firstly, rotating said first rotating element to a stop position corresponding to said desired water temperature, and secondly, rotating said second rotating element to a stop position where said second mark meets said first mark; and said mixing valve is capable of retrieving said desired water temperature after said mixing valve being pre-set to said desired water temperature, in which, said first rotating element is rotated to a stop position where said second mark meets said first mark. 4. A mixing valve assembly comprising a mixing valve including a valve body having: a first rotating element connected to a valve stem for turning on and off said mixing valve, and for adjusting outlet water temperature of said mixing valve; and a first mark on said first rotating element; and an escutcheon forming a water-tight enclosure for covering a hole in a wall where the valve body of said mixing valve penetrates through; and a second rotating element that is rotatably connected to said escutcheon in the axial direction of said valve stem of said mixing valve, and maintains a water-tight seal of said escutcheon while being rotated; and a second mark on said second rotating element; wherein: a relative movement between said first and second marks occurs when said first rotating element is rotated; and said mixing valve is capable of pre-setting said outlet water temperature to a desired water temperature by, firstly, rotating said first rotating element to a stop position corresponding to said desired water temperature, and secondly, rotating said second rotating element to a stop position where said second mark meets said first mark; and said mixing valve is capable of retrieving said desired water temperature after said mixing valve being pre-set to said desired water temperature, in which, said first rotating element is rotated to a stop position where said first mark meets said second mark. 5. The mixing valve according to claim 1, 3 or 4, in which, said second rotating element is provided with forward and rearward stops that restrict maximum forward and rearward axial movements of said second rotating element respectively, in which, said forward and rearward stops do not require use of set screws. 6. The mixing valve according to claim 1, 3 or 4, in which, said first and second marks are strategically located so that they provide clear visibility when they meet each other.
