Navigating the serene terrains of Hou Xiantang's paintings, the audience finds itself transported beyond the mundane. Hou employs a distinct M-shaped brush stroke that lends an intriguing blend of vitality and enigma to the mountainous landscapes he presents as his ultimate "hidden paradise." This technique affords remarkable versatility, layering strokes to evoke towering, rugged mountains or employing a softer touch to suggest lush, dense forests.

Ink wash painting, unlike oil painting, lacks the benefit of coverage and opacity. One single misplaced stroke has the power to disrupt the entire artistic pursuit. There is no such thing as white ink; all white spaces are deliberate omissions. This juxtaposition of reserved white spaces—clouds, mist, ripples, and streams—demands a high level of proficiency with the brush and a heightened awareness of aesthetics.
