Manbao peered out of the window and spotted Bai Erlang still sitting outside with Datou eating small fish, so she immediately collected the letter and sat down at the desk to start writing a reply.
The letter from Bai Shanbao had arrived along with Ms. Liu's, as they hadn't entrusted it to passing merchants for delivery. Such letters could easily get lost and would arrive very late.
Travel in this era was arduous, with too many uncontrollable factors. If a merchant fell ill on the way, or decided midway to go elsewhere, their letters would undoubtedly wander with the merchant.
It could take three to four months, or even two to three years for a letter to finally reach its addressee.
The Bai Family certainly wouldn't choose such a risky means; they would send their own servants back and forth to deliver letters.
