Judging from your question, you mainly focus on eating, playing, and leisure, rather than shopping.

Play along Binjiang Road from south to north.

There is a Catholic church on the southernmost side of Binjiang Road, you can go and see it.

Facing Binjiang Road, you can see it from far away.

Binjiang Road and Heping Road are Golden Streets. There are many shops, shopping malls, and famous brand stores. You can go shopping as you like.

The snack street is on Liaoning Road, but there are very few seats, so you can buy and eat while walking.

Although there are different opinions, since it’s here, it doesn’t hurt to try it.

I strongly recommend that you go to one of the five nearby teahouses in the afternoon to listen to a cross talk show.

Firstly, it was about Tianjin folk customs, and secondly, they spent the whole morning shopping and found a pleasant place to rest. Afterwards, the two of them could often recall funny jokes.

These teahouses are not expensive, the ticket price is 15-30 yuan per person, and the tea is usually free (I haven’t been there since May Day).

You can buy some food at the snack street and take it to the teahouse to eat and listen (don’t laugh).

There are 5 teahouses near Binjiang Road with cross talk (the first 5 "addresses of each garden..." in the attached table), all within a 10-minute walk.

Please see the attached schedule for performance times and specific locations.

After listening to the cross talk, it’s up to you whether you want to continue shopping or go home.

My advice will make the trip feel worthwhile to both of you, especially afterward.
