Guo Xuehu's hours spent studying at the library and sketching around Taipei paid off. In 1928, his painting titled "Scenery Near Yuan Shan" (Maruyama fukin) received a special award at the second Taiwan Fine Arts Exhibition. Moreover, the Government-General purchased the work at a very high price of 500/600 yen. The official salon and the library brought Guo Xuehu into the orbit of Japan's imperial art world. His relationship with colonial institutions would only expand in the subsequent years, as the Culture and Education Bureau, Tainan Public Hall, and Navy Officer's Department would purchase his salon works.

Scholars have pointed out that the coloring of this painting is similar to the painting style of a Japanese juror and settler artist, Gōhara Kotō (1887-1965). Guo Xuehu is said to have admired Gōhara's set of three hanging scrolls on view at the first Taiwan Fine Arts Exhibition, depicting birds and flowers (for black and white reproductions click here, the work is presumably lost) (New visions, 248). In 1929, Guo Xuehu began studying with Gōhara and joined the Sendansha (Sandalwood Society, 1930-36), an exhibition group founded by Gōhara Kotō and another established nihonga settler-artist, Kinoshita Seigai (1887-1988).

Guo Xuehu's exhibition record speaks to the a great appeal of his paintings to his contemporaries. In total, his paintings were accepted to all annual salons in Taiwan. Moreover, he received special awards in 1928, 1929, 1931, 1932; the Taiten Prize in 1930 and 1931; the Tainichi Prize in 1932; and, the Asahi Prize in 1935. Starting from 1933, his works were exempted from review to the salon (mukansa). Except for one figure painting, all of his salon works were landscapes, sites in nature or around the city. 

His works demonstrate his technical mastery of complex compositions and great attention to detail. The artist explored different techniques and styles: he produced works in lush greens and drip-in technique reminiscent of Rimpa painting ("Scenery Near Yuan Shan" 1928; "After the Rain" 1931), applied perspective and vivid colors to capture a bustling urban scene ("Prosperity of South Street" 1930), and carried out an unconventional experiment with ink and paper to convey a mysterious evening mood ("Solitude" 1933). In his depiction of the Dihua Street in the Da Dao Cheng's Yon-lo District, he deliberately chose to depart from naturalistic depiction by extending the buildings upward and foreshortening the depth of the street to convey prosperity of shops on this street with many signboards in Chinese and Japanese (New Visions, 35-36). He strove to achieve the right balance between naturalism (sketching from nature, attention to detail, elements of one-point perspective) and an overall decorative quality of the painting surface (distribution of color, composition, use of outlines or lack thereof etc.) in a way that spoke to Japanese jurors and audiences familiar with nihonga (Compare Yen on "Scenery Near Yuan Shan" YEN p. 103).

The appeal went beyond technique and painting style, however. His works depicted Taiwan's scenery, a topic of growing interest to both Japanese and Taiwanese-Chinese viewers. Taiwan was changing. With every year, Japanese presence on the island left a more visible mark. As a landscape artist, he captured that moment.

"Scenery Near Yuan Shan" (1928) depicts a site in Taipei well familiar to its citizens. The viewer's eyesight takes in the maize, sunflowers, and fields in the lower part of the painting, then travels through the hilly park, finally to discover an iron Truss bridge and street lamps towards the left. A small flock of birds draws the viewer's attention to the landscape on the other site of the bridge, not represented in the painting - the grounds of the Taiwan Shrine (Taiwan jinja). The whole area of the park and the shrine was developed in the early years of colonial rule. Even the maize and sunflowers are not local plants but possibly crops introduced by the Japanese. The white boundary tablet in the lower side of the painting indicates that the land has been measured and defined by ownership. (New visions 29-30). The lush greens evoke the natural beauty of the landscape, yet it is a clearly man-made site, imbued with historical and political significance.

Similarly, the double prize-winning "After the Rain" (1931) depicts a site of great historical import in Taiwan's colonial history, the Zhishan Cliff (Shibayama in Japanese), where, in 1896, six pioneer Japanese teachers were assassinated. In other words, the flourishing garden and park rest atop a site of sacrifice for the imperial cause and of anti-colonial resistance. A pathway through the carefully cultivated fields leads the eyesight into an elevated area of the park, with two distinct rooftops visible amidst foliage: that of a memorial shrine established to commemorate their deaths, and a local temple. The two buildings were in fact situated apart from each other, yet the artist depicted them in close proximity. The memorial shrine was completed only in 1930, a year before this painting. The juxtaposition suggests a peaceful integration of Japanese and Taiwanese elements (Compare: YEN p. 103. New Visions, 254).

Guo Xuehu's works were on view in the tōyōga division at the Taiwan Fine Arts Exhibition. They shared their artistic concerns and even subject matter with nihonga, as many Japanese artists traveled to Taiwan in search of a distinct subject matter for their figure and landscape paintings.

In 1935, Taiwan Government-General Library gave Guo Xuehu a special award of 500 yen. This award was given out only once a decade and provided enough money to sustain a small family for a year. The same year, his painting "The Junk" (Janku) on view at the ninth salon won the Asahi Award and was purchased for the exorbitant amount of 1500 yen by the Taipei Police Station (Ex. cat. 1989 p. 208). Within the span of less then ten years, Guo Xuehu established himself as a successful professional artist.
