 ltraviolet (UV) radiation\, high-mass stars dominate the evolutionary proc
 esses of galaxies. Nevertheless\, their formation and evolutionary mechani
 sms remain poorly understood. To conduct a statistical investigation of hi
 gh-mass star formation in the Milky Way\, we have launched the ALMA-ATOMS/
 QUARKS survey using the Atacama Large Millimeter/submillimeter Array (ALMA
 ). This program has observed approximately 140 high-mass proto-clusters in
  Band 3 and Band 6\, achieving an angular resolution of ~0.3 arcseconds. T
 he key scientific objectives of the ALMA-ATOMS/QUARKS survey are: (i) to a
 dvance our understanding of the dense gas star formation law by characteri
 zing the spatial distributions of diverse dense gas tracers in a large sam
 ple of Galactic clumps and quantifying the fraction of molecular gas invol
 ved in star formation\; (ii) to explore how stellar feedback from newly fo
 rmed OB (proto)stars shapes the surrounding gas distribution and modulates
  subsequent star formation within their host clumps\; (iii) to resolve fil
 amentary structures and elucidate their fundamental roles in proto-cluster
  assembly\; and (iv) to search for massive protostellar disks and investig
 ate the multi-scale gas accretion mechanisms that govern protostellar mass
  growth\; and so on. In this talk\, I will present the current progress of
  this survey and outline its future observational and analytical plans.Bio
 graphy:Dr. Tie Liu received his PhD degree from Peking University in 2013.
  Subsequently\, he pursued research careers in Chile\, South Korea and the
  United States as KASI Fellow and EACOA Fellow. He returned to China and j
 oined the Shanghai Astronomical Observatory in September 2019\, where he h
 as served as an Associate Researcher and then a Researcher professor. Curr
 ently\, he presides over a number of key scientific research projects\, in
 cluding the National Key R&D Program of China. His research primarily focu
 ses on observational studies of ISM and star formation in the Milky Way us
 ing world-class large radio telescopes\, such as ALMA\, SMA\, JCMT\, NRO 4
 5-m\, and FAST. As the Principal Investigator (PI)\, he has led several la
 rge international collaborative observational projects\, including JCMT-SC
 OPE\, ALMA-ATOMS/QUARKS\, and ALMASOP.\n\nhttps://indico-tdli.sjtu.edu.cn/
