1. There's a custom in my family that visiting the pagoda on the first day of every lunar month.

=> There's a custom = S + have/has/had + tradition.

2. Tet's consider a holiday. However, people are even busier than ordinary days.

Vì however chỉ đứng trước dấu "." và sau dấu ",".

Hơn nữa, Vế đầu ( Tet... ) là vế chính nên nó được bỏ lên đầu.
