a type of liquid glue, used, for example, by actors for sticking false hair to their faces

The most realistic fake moustaches are built up one hair at a time with spirit gum. 最逼真的假胡子是用灵胶一根一根地粘起来的。

Go to a place that sells stage makeup, get some spirit gum, and some fake hair and just glue it on a few pieces at a time. 去卖舞台化妆品的地方，买点快干胶水和假发，一次粘上几片就可以了。
