Buying tickets through KLOOK is very convenient. Even if you buy them right in front of the zoo's ticket counter, it only takes a minute to use the app, buy the QR code, and receive it instantly. Then, you can use the QR code to enter, which is more convenient than buying tickets at the on-site ticket counter. Buying tickets on-site is more expensive than buying them online. Additionally, buying tickets on-site only allows for electronic payments; cash is not accepted, just like with KLOOK. However, you don't have to wait in line on-site, so KLOOK is more convenient and worth recommending.
