Why is "Chân Lạp" trending?

Wikipedia Overview

"Chenla" or "Zhenla" was the name given in Chinese accounts of an entity that sent tributes to Chinese emperors. The word "Chenla" or "Zhenla" and likewise Funan are unknown in the Old Khmer language. Folk etymology attempts to link Chenla (真臘) to a translation of its Chinese name as "Pure Beeswax", which was one of its regional commodities mentioned in Chinese annals. It has been suggested that the name means "Defeated Siam" as Zhenla has been reconstructed to Tsienliäp in Tang dynasty pronunciation, which is similar in sound to the Cambodian town Siem Reap whose name is often taken to mean "Flattened Siam". However, it has been pointed out that this derivation is problematic as conflicts between Siam and Cambodia occurred centuries after the name was first used. Therefore, although the names Chenla and Siem Reap could perhaps be related, Michael Vickery argued that the original meanings of both names are unknown.
