Although it doesn't state whether a heliocentric model was proposed, I'd imagine some Chinese scholars entertained the possibility. Foremost, they had to overcome the accepted beliefs of their time, such as whether the Earth was flat and there could be spherical celestial bodies in the heavens. Yu Xi seems to be one of the closest astronomers of Ancient China to observe a celestial phenomenon that can be attributed to heliocentrism.
According to Yu Xi's Wiki:
In 336 AD Yu Xi wrote the An Tian Lun (安天論; Discussion of Whether the
Heavens Are At Rest or Disquisition on the Conformation of the
Heavens). In it he described the precession of the equinoxes (i.e.
axial precession). He observed that the position of the sun during
the winter solstice had drifted roughly one degree over the course of
fifty years relative to the position of the stars. This was the
same discovery made earlier by the ancient Greek astronomer Hipparchus*
(c. 190-120 BC), who found that the measurements for either the sun's
path around the ecliptic to the vernal equinox or the sun's relative
position to the stars were not equal in length.
Furthermore, he states, like Zhang Heng before him, that the heavens were infinite and "motionless" (in this regard motionless in relation to the Earth). It's possible other astronomers also entertained this idea, but much of Imperial courts were heavily influenced on Confucian beliefs, which were based on the observable universe.
Yu Xi wrote a critical analysis of the huntian (渾天) theory of the
celestial sphere, arguing that the heavens surrounding the earth were
infinite and motionless. He advanced the idea that the shape of the
earth was either square or round, but that it had to correspond to the
shape of the heavens enveloping it. The huntian theory, as mentioned
by Luoxia Hong (fl. 140-104 BC) and fully described by the Eastern-Han
scholar-official Zhang Heng (78-139 AD), insisted that the heavens
were spherical and that the earth was like an egg yolk at its
center.[6] Yu Xi's ideas about the infinity of outer space seem to
echo Zhang's ideas of endless space even beyond the celestial sphere.
Although mainstream Chinese science before European influence in the
17th century surmised that the Earth was flat and square-shaped, some
scholars, such as Yuan-era mathematician Li Ye (1192-1279 AD),
proposed the idea that it was spherical like the heavens.
*The fact that Xu Yi made the same observation as Hipparchus is significant by the fact that Hipparchus is considered the first to propose the Heliocentric model (yet abandoned this work as the calculated orbits weren't perfectly cylindrical, the criteria at the time). We can speculate that this may also have influenced Xu Yi and other ancient astronomers' pursuits to not continue studying heliocentrism further.
Hipparchus is thought to be the first to calculate a heliocentric
system,[6] but he abandoned his work because the calculations showed
the orbits were not perfectly circular as believed to be mandatory by
the science of the time. As an astronomer of antiquity, his influence,
supported by ideas from Aristotle, held sway for nearly 2000 years,
until the heliocentric model of Copernicus.
