Planets are known to orbit giant stars, yet there is a shortage of planetsorbiting within ~0.5 AU (P<100 days). First-ascent giants have not expandedenough to engulf such planets, but tidal forces can bring planets to thesurface of the star far beyond the stellar radius. So the question remains: aretidal forces strong enough in these stars to engulf all the missing planets? Wedescribe a high-cadence observational program to obtain precise radialvelocities of bright giants from Weihai Observatory of Shandong University. Wepresent data on the planet host Beta Gem (HD 62509), confirming our ability toderive accurate and precise velocities; our data achieve an rms of 7.3 m/sabout the Keplerian orbit fit. This planet-search programme currently receives~100 nights per year, allowing us to aggressively pursue short-period planetsto determine whether they are truly absent.
