Technology is not true or false, but if you have enough technology, it may be. Lao Bu's steamed stuffed bun technology is not updated. I study there, but I can't go home to open a shop. Then I went to Tianjin and didn't choose Lao Bu. Anyway, I have seen many buns in Tianjin, including my aunt's, and they are not very delicious, but Lu Ji's buns are really delicious. I'm going to study in luji again.
