A few years ago I bought my friend an entire bottle of Moutai Baiju.
That's sounds cool, why did you buy your friend a bottle of Moutai?
Because I said I would do so
Moutai is a very expensive baijiu and it's a nice and considerate gift to give to a friend if he or she enjoys drinking liquor. Giving gifts is a part of being a good friend and by gifting your friend Moutai, it shows that you value your friends very much.
I just want to recruit people who like doing the same stuff I do, things that I like.
That's fine, you're to be commended for buying such nice gifts. I'm sure that friend still remembers it fondly.
