Why did Thai Language borrow Middle Chinese for numerals 2-4 (song, sam, si), 7-10 (chet, pet, kao, sip), 20 (yi sip) & -1 (et, in higher numerals) whereas numerals 5 (ha < *lŋa / *sŋa) & 6 (hok < *krok ) seem to be Old Chinese loanwords?

為甚麼泰語的 2(song 雙)、3(sam 三)、4(si 四)、7(chet 七)、8(pet 八)、9(kao 九)、10(sip 十)、-1(et 一)、20(yi sip 二十)、萬(mɯ̀ːn)都借自中古漢語(閩/粵方言);而 5(ha < *lŋa / *sŋa )和 6 (hok < *krok) 則像是借自上古漢語?
