“…Geophysical techniques are widely used to investigate the subsoil for the detection of features of archaeological interest (Deiana, Leucci, & Martorana, 2018; Gaffney, 2008; Liu, Shi, Wang, & Yu, 2018; Shi et al, 2015; Shi, Hobbs, Max, Tian, & Jiang, 2017). Tombs are common archaeological detection objects and geophysical methods are usually used to investigate their location (Atya et al, 2005; Oh, Abdallatif, & Suh, 2008; Piscitelli et al, 2007; Rabbel et al, 2015) and to detect their internal structure (Booth, Szpakowska, Pischikova, & Griffin, 2015; Kamei, Marukawa, Kudo, Nishimura, & Nakai, 2000; Nuzzo, Leucci, & Negri, 2009; Pipan, Baradello, Forte, & Finetti, 2001; Rodrigues, Porsani, Santos, DeBlasis, & Giannini, 2009; Sarris et al, 2007). The large‐scale mausoleums that existed in the middle and late periods of the Southern Song Dynasty (SSD, 1127–1279 ce ) in China are valued by archaeologists for their unique shape and rich cultural connotations (Zhejiang Institute of Archaeology, 2009).…”
