Angka-AngkaSaat malam hari, ada masalah dalam menilai: varietas yang dapat diperdagangkan pada hari Sabtu pagi, varietas yang berakhir pada pukul 23:30 di Dongguan, varietas yang berakhir pada pukul 2:30 di Shanghai.

edwardgywBaiklah.

Angka-AngkaSaat ini, mereka masih berada di luar kota. Dia mengatakan, "Saya tidak tahu apa yang terjadi". Varietas yang terjual setelah jam 0:00 malam dapat diperdagangkan pada hari Sabtu pagi.

edwardgywJadi, apa jenis-jenis nightstand yang ada, dan di mana mereka bisa ditemukan atau lebih tepatnya, saya menambahkannya.
